Framebuffer zero used after being destroyed in the Context destructor. #950

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This is a small issue which shows up when I tried to use AppVerifier with ANGLE 
end2end.

When the context is destroyed, it needs to delete all the framebuffers. When a 
bound framebuffer is destroyed, it is detached of the read and draw binding 
points and the framebuffer zero is bound instead. Unfortunately the framebuffer 
zero is destroyed first hence the we try to attach a framebuffer which is 
already destroyed.

Fixed, but assigning to me for a unit test when possible.
