[Mesa-dev] [RFC 0/3] Fix several segmentation faults related to depth buffer

[Alon Levy]

Fixes three segmentation faults where it is wrongly assumed the depth buffer's
renderbuffer's region is not NULL.

735794 - verified to be fixed by these three patches (these three apply
to 7.11 almost cleanly, just the second requires minor changes).

Related RHBZs (maybe solved as well, didn't reproduce):
