2014-02-27 Nightly build

The Epic Citadel demo crashes with my regular Nightly profile. It's not extension related since it still crashes with all extensions disabled. It crashes after loading finishes, when the progressbar starts filling second time.

Example crash IDs:
bp-ccaf12f4-ece8-4f12-9377-280d32140228
bp-b0aee88a-c869-4cdd-9ff9-96b9a2140228

I managed to get a regression range using mozregression and using my profile.

Also attaching about:support contents. I'd be happy to provide my profile folder to a Mozilla developer if needed.

Looks like JIT crashes?

Reporter, are you willing to try using builds from http://inbound-archive.pub.build.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-inbound-win32/ to further narrow the regression range?  We seem to have those back to September, though finding the ones for a particular date is a bit annoying.  :(

I'll get on it (mozregression tried to bisect inbound for me but it stalled).

This looks a lot like a bug I fixed yesterday. The patch should be in the next Nightly, would you mind giving it a try once it's out?

Comment 5

Some time (30mins) before filing this bug I tried the last green build linked from tbpl and it also failed. In any case, I will try the next Nightly ofcourse.

You could also try these two builds:

http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32-pgo/1393552810/
http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32-pgo/1393531202/

[Jan de Mooij [:jandem]]

(If I'm right, only one of them should crash. If they both crash it's another bug.)

You were right jandem. Thanks for saving me some frustration trying to bisect inbound :)

The new Nightly is out and the underlying but is fixed. WFM or DUPE?

Comment 10

[Sylvestre Ledru [:Sylvestre]]

Does this bug affect 29 ? (the tracking was requested for 29)

Comment 11

[Boris Zbarsky [:bzbarsky]]

So was this fixed by bug 977538?

Comment 12

[Jan de Mooij [:jandem]]

Yup.
