Bug detailed description:
-----------------------------
It fails on i965 platforms with mesa master branch, and works well on 10.1
branch.
Bisect shows:4caa9db71ce05dc2cc86177ca42655c2011fbe4a is the first bad commit.

mesa/sso: Add gl_pipeline_object parameter to _mesa_use_shader_program
Extend use_shader_program to support a different target. Allow to reuse the
function to update the pipeline state. Note I bypass the flush when target
isn't current. Maybe it would be better to create a new UseProgramStages
driver function
This was originally included in another patch, but it was split out by
Ian Romanick.
