736815 - crash in js_ValueToBoolean

Status: RESOLVED FIXED

Description

[Scoobidiver (away)]

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:

Comment 1

[Scoobidiver (away)]

It's #6 top crasher in 14.0a1 over the last 3 days.

Comment 2

[Bob Clary [:bc:]]

This is probably bug 737447 which has a reproducible url.

Comment 3

[Luke Wagner [:luke]]

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.

Comment 4

[David Mandelin [:dmandelin]]

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?

Comment 5

[Scoobidiver (away)]

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 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. :)

I would have done it but you can't do that for security sensitive bugs.
