Bug detailed description:
------------------------- 
It segfaults at mesa 8.0 branch on pineview. It also segfaults on mesa master branch. Below cases also segfault:
depth-stencil(advanced.packed_depth_stencil_int.shader1D)
depth-stencil(advanced.packed_depth_stencil_int.shader2D) 
depth-stencil(advanced.packed_depth_stencil_int.shader1D_sized) 
(depth-stencil(advanced.packed_depth_stencil_int.shader2D_sized)
Following case fails on pineview:
(GL30)depth-stencil(advanced.packed_depth_stencil_border)
 
Bisect fails due to some mesa commit build failure. The last known bad commit is
Mesa(8.0)c85402aba91755808729fadf57a9f92285f4e61a, the last known good commit is Mesa(7.11)7722a54e60c9da080b557d6596e4c9d363ead515.
