This bug was filed from the Socorro interface and is report bp-3b40b941-49b4-4c83-beff-51ecc2160417. ============================================================= We've gotten a handful of these crashes in each of the past 3 Nightly builds (20160415030231, 20160416030220, 20160417030601). The stack is different to the one from bug 1256500 because the second frame is different: > 0 xul.dll nsStyleContext::StyleDisplay() obj-firefox/dist/include/nsStyleStructList.h > 1 xul.dll

dbaron, any idea if this is related to bug 1256500?
Flags: needinfo?(dbaron)
So in this particular minidump (the one from comment 0), nsStyleContext::StyleDisplay is being called with a null |this| pointer. We crash when trying to look at mCachedStyleData, which I did check against the correct source that it is at offset 0x40. Looking up a frame, at ZIndexForFrame, mStyleContext should be at offset 0x20 (leaving room for the vtable pointer at the start, I think), which agrees with the disassembly. That also shows the style context in RCX (as null), and the aFrame in RDI being 000000ABC3CD6520. (The !aFrame->IsAbsPosContainingBlock gets inlined into a call to nsStyleContext::StyleDisplay and then a call to nsStyleDisplay::IsAbsPosContainingBlock.) 000000ABC3CD6520 does seem consistent with heap addresses a few frames down on the stack (e.g., in nsSubDocumentFrame::BuildDisplayList). No bright ideas, really, although it's certainly *not* bug 1256500.
I'd be interested in extension / module correlations for this. (And I do think I've seen crashes like this one on release when I was looking through the nsStyleContext::StyleDisplay crashes; I just filed one of the patterns because I saw what was going on.)
(In reply to David Baron [:dbaron] ⌚️UTC-7 from comment #4) > I'd be interested in extension / module correlations for this. "none found", as best as I can tell.
"None found" means the report is broken, not that there's nothing interesting in the information that would be there if it were working
Summary: crash in nsStyleContext::StyleDisplay → crash in nsStyleContext::StyleDisplay, called from ZIndexForFrame
(The main thing I want out of that abort message is the display item type, but I figure the pointers won't hurt while I'm there.)
So looking at the crash reports again, I was misled by the Visual Studio debugger. In bp-3eab56d0-ad64-4764-a65d-f909a2160425, we're calling nsStyleContext::StyleDisplay with this=0x7ffffffff0de7fff, which is the frame poison pattern. bp-780f5e2d-97b9-4485-bc13-8e9262160425 appears to be the same, although I didn't look as closely. So my debugging patch isn't actually going to work.
... but I should instead test the StyleContext() pointer against mozPoisonValue()
So crashes with the debugging info show up at: https://crash-stats.mozilla.com/signature/?date=%3E%3D2016-04-27&product=Firefox&release_channel=nightly&signature=mozalloc_abort+%7C+NS_DebugBreak+%7C+IsZOrderLEQ&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&page=1#reports So far there's only one: bp-fecc85fb-6390-40d8-b20f-427742160429 and it has: ###!!! ABORT: bad display item 1e1b2027980 type Plugin frame 1e19f569278 (The abort message isn't in crash-stats, but the MSVC debugger shows the value of |buf| in NS_DebugBreak.) It would be nice to get a few more to confirm a pattern.

Looks like this is still crashing (at a low rate), so I'll keep the bug open for now.
