It was me who crashed with that stack, btw. But I don't have str or a testcase.

Comment 2

[Martijn Wargers (dead)]

Ok, the testcase in bug 749816 seems to trigger this crash consistently now: https://bugzilla.mozilla.org/attachment.cgi?id=619195
Make sure you use the latest trunk build to get this crash, otherwise you would get the crash from bug 749816.

Ok, this doesn't seem to crash anymore in current trunk build, so I guess this was fixed by bug 748531.
However, I still occasionally get this crash, I haven't figured out a testcase yet.

Do you have a crash report ID from a crash on a build after bug 748531 landed?

Attachment: testcase2

This testcase still crashes in a trunk build from yesterday.

Here is a crash report from it:

It's bug 752426 (same stack except the first frames).

Comment 7

[Martijn Wargers (dead)]

Sorry, but aren't those bugs the same? Perhaps bug 748531 did change the stacktrace or something?

There are about one crash per buildID for this bug while there are about 110 crashes per buildID for bug 752426.

Yeah, what scoobi said. This one is the same as bug 752426, which is a regression from bug 750846. That crash might be obscuring this crash ("this" == bug 749915) which is different because it existed prior to bug 750846.
