This bug was filed from the Socorro interface and is report bp-00e63b79-d80b-4130-9c91-1963b2150816. ============================================================= Crash with latest Fedora 22 KDE using pretty much all experimental layers features (APZ, acceleration forced, use-image-offscreen-surfaces). No STR. Happened two times already. Here's the previous report (August 1st): bp-3555e5a8-bbff-45b4-aafe-d7b452150801
Looks like something bad is happening in the destructor. We should be able to figure out what by looking at the disassembly.
The only scenario I could find in the disassembly where we could jump to 0x0 would be if we're trying to call a symbol in a destroyed GLContext. The vtables of the participating classes seem sane. We should modify the code here to check the result of GLContext::MakeCurrent before deleting the GL objects.
