The opt_sampler_eot optimisation of fs_visitor effectively assumes that it is running on a fragment shader because it casts the program key to a brw_wm_prog_key. However on Skylake fs_visitor can also be used for vertex shaders. It looks like this usually works anyway because the optimisation is skipped if key->nr_color_regions != 1. However for a vertex shader the key is actually a brw_vs_prog_key so the space for nr_color_regions is probably taken up by key->base.program_string_id. This can end up making nr_color_regions be 1 in which case the function will later assert when the last instruction is not FS_OPCODE_FB_WRITE. This was making the DEQP test suite assert. Presumably this only happens there because that compiles a lot of shaders so it would end up with a high value for program_string_id.
