Same comments as in bug 601086 :-)
Comment 3 Benoit Jacob [:bjacob] (mostly away) 2010-10-01 04:01:32 PDT
Ah no... your call stack here is weirder. Will try to reproduce with MOZ_GL_DEBUG=1 with the patch from bug 597881.
Comment 4 Benoit Jacob [:bjacob] (mostly away) 2010-10-01 14:44:54 PDT
Sorry, I can't reproduce here, with ANGLE enabled, with or without GL debug mode.
Comment 5 Benoit Jacob [:bjacob] (mostly away) 2010-10-01 14:45:37 PDT
(on windows 7)
Comment 6 Benoit Jacob [:bjacob] (mostly away) 2010-12-10 13:22:35 PST
We've had a big ANGLE upgrade recently. Can you please retry, and close this bug if the crash is gone?
Comment 7 Benoit Jacob [:bjacob] (mostly away) 2010-12-10 13:23:23 PST
Also, if the bug is still present, please rerun firefox, go to about:crashes, and give us the relevant link.
Comment 8 Benoit Jacob [:bjacob] (mostly away) 2010-12-13 14:21:58 PST
Test case doesn't crash anymore here, while it used to.
Also, this is possibly the same as bug 601086 which got fixed as Angle bug

Comment 9 Benoit Jacob [:bjacob] (mostly away) 2010-12-13 14:22:53 PST
Sorry, rereading above commens --- I never could reproduce. Still propose WORKSFORME.

Christoph: thanks for the testcase. Can you please provide a callstack? Would help to figure if there's a security risk.
