Piglit e59e81fde566b114e48910e63a9d43501c00cee2 destroys the context at the exit of each piglit test.
This works fine everywhere but on g965 spec.!opengl 1_2.tex3d-maxsize, which crashes with:
Mesa: User error: GL_OUT_OF_MEMORY in glTexImage3D(image too large: 2048 x 2048 x 2048, GL_RGBA8 format)
intel_do_flush_locked failed: Argument list too long
tex3d-maxsize: /home/jenkins/workspace/Leeroy/repos/mesa/src/mesa/vbo/vbo_exec_api.c:1178: vbo_exec_FlushVertices: Assertion `exec->flush_call_depth == 1' failed.
Previously, the test failed instead of crashing.
This seems like a hardware limitation associated with a change to tests, not a regression in mesa.
