It's a residual crash but there's a spike in crashes from 14.0a1/20120317, all in 64-bit builds. The regression range for the spike is: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=e5f6caa40409&tochange=ecaad3ae9964 It might be a regression from bug 730497 or bug 733950. 64-bit stacks are various and probably buggy: Frame Module Signature [Expand] Source 0 xul.dll js_ValueToBoolean js/src/jsbool.cpp:222 1 xul.dll js::Interpret js/src/jsinterp.cpp:1938 2 xul.dll js::mjit::stubs::TypeBarrierHelper js/src/methodjit/StubCalls.cpp:1651 ...

It's #6 top crasher in 14.0a1 over the last 3 days.
This is probably bug 737447 which has a reproducible url.
I agree with comment 2. The fix is on m-c and should be in the next nightly, so let's see if this spike goes down.
Dropped off to almost nothing following 3/22. What do we do with these when they go away? Do we close WFM? Take off tracking? Mark as dup?
The latest crash in the trunk happened in 14.0a1/20120322. The working range is: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=5c13fce74f83&tochange=ab2ff3b5611f It was fixed by bug 737388, a dupe of bug 737447.

I'd usually go WFM if we don't know what fixed it, DUPE to the fix if we know what it was. (In reply to Scoobidiver from comment #5) > It was fixed by bug 737388, a dupe of bug 737447. In that case, for correctness, it would have made sense to mark it as a dupe of the bug that contains the patch that landed and fixed this. I won't change around this one though, no need for bugspamming, the important fact is that it's RESOLVED. :)
