The current #7 topcrash occurs with a signature of GraphWalker::DoWalk(nsDeque&). This crash occurs across platforms (Mac and Windows so far). All crash signatures look like this one, taken from bp-a6c2a662-3402-487e-b4b7-a45442090623, sometimes ending on frame 0, sometimes with the GraphWalker::DoWalk line not repeated: Frame Module Signature Source 0 xul.dll GraphWalker::DoWalk(nsDeque&) xpcom/base/nsCycleCollector.cpp:1186 1 xul.dll GraphWalker::DoWalk(nsDeque&) xpcom/base/nsCycleCollector.cpp:1182 2 xul.dll GraphWalker::WalkFromRoots(GCGraph&) xpcom/base/nsCycleCollector.cpp:1170 3 xul.dll nsCycleCollector::BeginCollection() xpcom/base/nsCycleCollector.cpp:2469 Lars: Can you grab some URLs for this issue from Socorro?

Haven't people learned by now? Porn kills (your computer). Seriously -- ask yourself. If some porn costs a lot of money or a subscription fee, why is some of it free? Is it perhaps because they have an alternate revenue stream: installing malware?

We have a Windows XP desktop suffering from these crashes when it runs Firefox 3.5.2, at least twice a day we encounter the problem. The only way we have been able to avoid this bug is to downgrade to the Firefox 3.0.xx branch. Often this occurs as soon as a link is clicked, but we find this hard to reproduce, it seems to be a very unpredictable occurrence. http://crash-stats.mozilla.com/report/index/46d27c8b-1809-4f90-bb17-9eff12090824 We may be having a related BSOD that crashes the entire system, which we never get while running Firefox 3.0.13 or earlier builds.

Comment 11•13 years ago

I'm not completely sure this is what causes the crash, but it seems like it potentially could. The iterator always increments mPointer, even after it just jumped to the start of a new block. I think one potential crash is that if mLastChild is set to the first pointer of the block, we could end up reading uninitialized memory because the iterator wouldn't stop since it would skip over the first pointer when doing operator++ (we do |child = pi->mFirstChild, child_end = pi->mLastChild; child != child_end; ++child|). When writing we don't use an iterator, so we do write to the first pointer of the block.

Comment 12•13 years ago

Comment on attachment 403974 [details] [diff] [review] v1 I think the code looks correct to me as it is now; the idea here is that iterators never point to the first pointer in a block; instead they point to the null sentinel at the end of the previous block (or in the pool itself) and dereferencing an iterator pointing to the sentinel (see operator*) returns the first pointer in that next block. I think this simplified things in other ways, e.g., by allowing us to create a valid iterator for the position after the end of a block before we've created the next block. I certainly should have documented that better, though.

Comment 13•13 years ago

This adds a number of aborts when certain conditions fail (pointers outside of blocks, null pointers where we didn't expect it, ...). I think we should try to land this on trunk to get some more data out of crash reports. I'm also still looking into adding more stuff on the stack, so we can get more out of minidumps.

Comment 14•13 years ago
|

I'd like to land this on trunk (only), but only until we have a couple of crash reports and minidumps. The aborts will probably move the crash to a different spot, but that should give us slightly more data to go on.

Comment 15•13 years ago
|
||
How is this going to help; NS_ABORT_IF_FALSE is DEBUG-only. Don't you want runtime aborts?
Comment 16•13 years ago
|
||
Other than that, this looks fine, though. Hopefully it won't be a performance hit. Sorry for the delay in getting to it...
Comment 17•13 years ago
|
||
Grmbl, I misread nsDebug.h, I'll switch to NS_RUNTIMEABORT. As for performance, I ran this through tryserver. Most of the numbers didn't really change, shutdown numbers changed a bit but some were down, so not sure how much I need to care about the ones that went up.
Comment 18•13 years ago
|
||
OK, r=dbaron with NS_RUNTIMEABORT (you need to write your own if-statements with that).
Comment 19•13 years ago
|
||
I actually went with a CC_RUNTIME_ABORT_IF_FALSE. I'll run this through tryserver again.

Are you sure they wouldn't show up under a different signature?
Comment 23•13 years ago

I check for signatures GraphWalker::DoWalk(nsDeque&), EdgePool::CheckIterator(Iterator&) and NodePool::CheckPtrInfo(PtrInfo*). I think that should catch them.

David, wouldn't those be for bug 437449? That one seemed related to thread-safety issues?
Comment 31•13 years ago
|
||
No, the MarkRoots crash has an almost identical statistical profile (core count distribution, module correlations) to this one, and I've been presuming it's the same underlying problem as this one. It's definitely not a threadsafety problem.

Well, MarkRoots doesn't have any of the debugging code.

Back to trying to figure things out from the assembly.
Comment 34•13 years ago
|
||
This bug causes frequent intermittent crashes on our Windows XP (SP3) box. There's no single action that precipitates a crash, appearing to be completely random.
Comment 35•13 years ago
|
||
We seem to sometimes have a bogus pointer to the next block. At first I thought we might have a bogus mFirstChild/mLastChild, so we'd walk randomly in the blocks and mistake a null PtrInfo* for the sentinel. But one of the crashes seems to be in the debug code I added, when walking the blocks. We walk the blocks using the blocksize, so in that case we just seem to have a bogus pointer at the right spot (last item in the array). I've looked at the block code again, don't see how it could happen. Maybe something else is corrupting our blocks' memory.
Comment 36•13 years ago
|

(In reply to comment #34) > This bug causes frequent intermittent crashes on our Windows XP (SP3) box. How frequent? Any chance we could get you to generate a full dump when it crashes (I think we can use DrWatson for that)?

(In reply to comment #18) > OK, r=dbaron with NS_RUNTIMEABORT (you need to write your own if-statements > with that). The NS_RUNTIMEABORT comments are scary, they sound to me like we wouldn't be able to trigger Breakpad on all platforms with that. Is that really what you want?
Comment 39•13 years ago
|
||
I think we should back out the debugging code on m-c and 1.9.2.
Comment 40•13 years ago
|
||
I agree about 1.9.2 (http://hg.mozilla.org/releases/mozilla-1.9.2/rev/96a497f82546 pushed earlier this week), but I don't see why we want to remove it from m-c yet. I think we should make sure it brings up breakpad, and see if anything shows up on crash-stats then.
Comment 41•13 years ago
|
||
I'd like to take this on trunk right now (unless we get a patch for bug 532490 in the meantime), and see if anything shows up in crash-stats.

I got this reported yesterday using Mozilla/5.0 (X11; U; Linux i686; rv:1.9.1.9pre) Gecko/20100208 SeaMonkey/2.0.4pre but when it happened again (I presume the same) today the reporter apparently ignored it. Today's current URL was http://us.imdb.com/media/rm1043761920/nm0209289 and I was attempting to return to http://us.imdb.com/name/nm0209289/mediaindex when the crash occurred. As I was attempting to count the number of tabs open (after restore/restart; 23 counted, 2 left to count, total 25) so as to proceed with this comment, it crashed again, and again reported failed to come up. SM was started from Konsole, and this is that window's resulting output: The program 'seamonkey-bin' received an X Window System error. This probably reflects a bug in the program. The error was 'RenderBadPicture (invalid Picture parameter)'. (Details: serial 1998858 error_code 182 request_code 155 minor_code 5) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

In 8 or so hours since comment 43 it crashed again, and again. Then the machine locked up and would not reboot into Linux. Main memory failed in a big way according to Memtest86+ 4.0.

is the debugging code talked about in comment 39 - 41 still on mozilla-central? that means it would be going out in beta. we should figure out if that's a good idea even if we don't have a good understanding of the cause of the crash or the fix yet.

It starts showing up as #4 top crasher in 4.0 RC1. Some comments say: "I was on the Addons page, and had clicked to go to top rated personas when it crashed." "was downloading some stuff and got booted off the internet" "Just looking around on Amazon"

https://tbpl.mozilla.org/php/getParsedLog.php?id=7562031&tree=Mozilla-Inbound - so there's one way to repro, run mochitest-other 50K times (or however many pushes we've actually triggered builds for), you'll hit it once.

Still appears consistently in the top 20 crashes for releases. Can we investigate this further?

This has been a top crash for a long time. The stack that's consistently high is GraphWalker<scanVisitor>::DoWalk(nsDeque&). We have just over 3500 on 10.0 in the past week. It's not a startup crash. Is there anything we can do to investigate this further?
Comment 73•11 years ago

About half of them are null-derefs. Maybe we can add some release-mode assertions to push around the crash to an earlier point where it would be more useful. I can take a look at that after I finish with a NoteXPCOMChild crashes.

WalkFromRoots is a similar signature that has shown up recently. Probably the same thing, just showing up differently in the crash reports due to different inlining.

Still a topcrash - mccr8, did you get somewhere with what you mentioned in comment #73?
Comment 77•11 years ago

I landed some assertions and un-inlining, that are currently on Nightly and Aurora. No progress in figuring out what the problem is. I don't know if I should back out the changes or not. I don't think it will affect performance to any measurable extent, but I could check. It isn't that common on Nightly. If you add the two GraphWalker signatures up on Nightly, you get a ranking of around 65. On Aurora, around 45. On beta, it shows up at 16. In release 11 it is at 12. I'm not sure why there is a such a large difference. I've noticed it before. It could be malware/junkware related, or perhaps our cycle collector optimizations, which make the CC touch less things in memory, just avoid touching bad things, so it isn't showing up here.

Still in the top 20 for crashes on release, Fx12.
Comment 79•10 years ago
|

This has gone way down in volume on all channels. Still a valid crash but removing the top crash keyword.
Keywords: topcrash
Comment 80•10 years ago
|

Currently this is around #90 on 16, #80 on 17. Either the move to a new compiler fixed a compiler bug, or with our CC optimizations we're touching bad memory less.

Different crashes: https://crash-stats.mozilla.com/search/?product=Firefox&signature=DoWalk&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature Accounts for 1824 crashes the last 7 days. Adding Thunderbird to the mix raises the number to 1860. Currently placed as #104 for 38.0.5 for GraphWalker<T>::DoWalk(nsDeque&) Top-crashes however only counts 948 of these, meaning half of them are other versions of firefox. Using the search numbers would place it in top 50 for Firefox top-crashes.

The bug is back -- 9 (!) years later: https://crash-stats.mozilla.com/report/index/cbfa60bf-d335-4ace-9e09-939341171106 I was not doing anything, I was away from the browser. The page with YouTube's subscriptions just died on its own.
