8 years ago
Build: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101014 Firefox/4.0b8pre

This is a new crash signature.
Crashes first appeared on 10/14th/10 at 4:21 in b8pre/20101013 build, that is almost one day after the release of this build.
So it can be caused by:
* an external update: MS patch tuesday (17 patches), java 1.6.22 update, extension update...
* or by the build itself.
If it is caused by the build, here is the regression range:

It is #13 top crasher in b8pre for the last week.

#5 topcrash on the trunk yesterday is probably a better reflection of where this is going.   first appeared yesterday on oct 14, in builds from oct 13 and 14.

this should probably block 4.0b7 if the change is headed for that branch too.

This looks like a tracer integration bug (all reports have stack traces like comment 0). This part was rewritten in bug 603044; should probably wait for that to land on mozilla-central.

There are no JS engine changes in the regression range. There may have been a change to some JS that runs as content (so that methodjit is on) that exposed a bug.

One problem might be that our version IDs are the same for builds from the TM repository. I've noticed this before, but keep forgetting to file a bug on it.
Historical analysis:

Aside from a lone report from a 9/23 build, this started with the 10/13 build, with 25 crashes on that day, but became 6-8x more common on 10/14 and afterward. Reasons why a spike like that could happen:

1. Something landed on TM for 10/13, got a hit a few times that day, then made it to m-c on 10/14 and started getting more hits.

2. Something busted it for 10/13, and another patch made it worse on 10/14.

3. Not many people tested the 10/13 build, many more got later builds.

Another interesting observation: Looking at the topcrashes on Socorro, it looks like xpconnect/compartments-related crashes had the same pattern: appear (or grow) on 10/13, grow (or grow again) on 10/14, while other types of crashes, and the crashes/ADU, did not show this. This makes #3 seem unlikely.

As noted in comment 4, nothing JS hit m-c on 10/12 (which would show up on 10/13), which makes #2 less likely.

*** #1 would seem particularly likely if m-c had 6-8x the ADUs that TM does. Does anyone know if that's true?

If it is #1, then it seems like it's basically compartments, but especially likely to be a patch that hit TM on 10/12 (for the 10/13 build), which would have hit m-c for the 10/14 build:

Nothing there looks pretty likely to me, though.

And this could still be just a trace integration bug that was exposed by compartments.
At least 3 of the report comments indicate the user was doing some routing in when they crashed, but I haven't yet been able to repro.

I don't see any with buildids later than Oct 20, I think there was merge that day that may have fixed this.
Going to WFM this bug, but if we see more reports please reopen.
