Very strange: nothing changed in this area on that day. But it could be that there was a latent bug there. This stack track, pointing to UnbindFakeBlackTextures, reminds me of bug 598517.

There are a couple of things that would really help here. First, having a stack trace from a debug build; second, having such a debug build with the patch from bug 597881 (it will soon get pushed anyway) applied and the MOZ_GL_DEBUG environment variable defined.

I tried to find when crash started, with webgl.enabled_for_all_sites;true.

Possible regression window .

These commits aren't directly related to the places found in the stack traces, so I suspect a preexisting problem. It would be very helpful to do as explained in comment 2; see also bug 600870 comment 1.

Is this the correct debug build: ftp://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32-debug/1286290590/firefox-4.0b7pre.en-US.win32.zip ?

Could the crash be caused by attempting to start the demo before it has been downloaded? The crash seems to happen only if I click the play button immediately after it appears.

Well, that debug build won't even start. The error message says something about parallel definitions (rough translation to English), application's event log and sxstrace.exe.

Here's a windbg log of the crash, using these instructions: https://developer.mozilla.org/index.php?title=en/How_to_get_a_stacktrace_with_WinDbg.

That is from the normal nightly build though. The debug builds won't run.

It doesn't crash anymore, so I think it got fixed with Bug 602183 - Crash [@ atioglxx.dll@0x15a1d3 ] on certain site. The url in bug 602183 caused a similar crash too for me (@ atioglxx.dll@0x3392e0). http://crash-stats.mozilla.com/report/index/bp-b956eabb-daf8-41a5-8f37-63c182101007
