Comment 1 Benoit Girard (:BenWa) 2012-05-11 10:04:47 PDT
marco: BenWa, I see cairo_debug_reset_static_data is being called before destroying a cairo surface

marco: maybe this is the problem with the crash

BenWa: marco: Is it mScreenReferenceSurface that's causing the crash?

BenWa: Your theory is good, you should try 2 things: 1) comment out that reset static data call, 2) set 'mScreenReferenceSurface = nsnull' before that function is called (forcing refcount to delete it)

BenWa: Calling cairo_debug_reset_static_data when we still have cairo data allocated is bad so that explains the crash. Its a bit curious that it's windows only however

This crash doesn't happen on trunk, it only happens with a patch from bug 705691.

LGTM. We should run a full set of test before landing it.

Pushed to try:

Sorry Macro I was distracted this Friday/weekend, lets get this back on track and landed.

I think we can land this:
