Bug detailed description:
-------------------------
glean cases pbo and texCube get segfault in intel_region_buffer
(intel=0x8136e30, region=0x0, flag=2)at intel_regions.c:440 recently because we
switch mesa to 7_5 branch. these two cases worked on mesa 7_4 branch and
master.
the backtrace of pbo from gdb is as below:
