Crash Data

This bug was filed from the Socorro interface and is 
report bp-eff90e4c-530b-4e7f-bf39-e7d532160602.
=============================================================

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile 
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.1.0 (git-525f3c2)
Looks like https://hg.mozilla.org/mozilla-central/annotate/34a8be4346a9/dom/canvas/WebGLTimerQuery.cpp#l48 might be null. This looks like it might be a simple fix.

It's possible that a WebGLTimerQuery is getting destroyed too late, after the destruction of the context itself. No other WebGL object seems to ensure that the GL context is alive at time of destruction.

I'll look into this.

Ah, looks like this is a dupe of bug 1275866, in which there's already a patch.
