The opt crash is gone \o/. Seems like this is the last one to get the debug build green.

Blake, you added this assertion in bug 976479. any idea whats going on?

Comment 3

[Blake Kaplan (:mrbkap) (inactive)]

See bug 989567, comment 1 (and therefore bug 924622). My understanding is that the graphics shutdown code is being reworked. Right now we race to shutdown with the main thread but I don't know when the shutdown rework is going to happen.

Comment 4

[Milan Sreckovic [:milan] (needinfo for best results)]

Shutdown code is in need of a rework, and it doesn't just involve graphics, as I understand it. There are a couple of bugs we're looking at, but we haven't actually embarked on the rework as such.
