I just started seeing an assertion failure in the gl-1.0-no-op-paths test on i915 (G33, specifically). I bisected to: commit c277fa394087272c79d65fc308d268fc768b91e5 Author: Brian Paul <brianp@vmware.com> Date: Wed Sep 30 11:29:13 2015 -0600 mesa: consolidate texture binding code Before, we were doing the actual _mesa_reference_texobj() call and ctx->Driver.BindTexture() and misc housekeeping in three different places. This consolidates the common code in a new bind_texture() function.
