With MESA_GLSL=nopt the code that was changed by the bisected commit is not being executed, so I think the real problem might be somewhere else. I guess you could try bisecting again with MESA_GLSL=nopt and maybe you'll come up with a different bad commit.
I might try this. Enrico, do you remember what the good revision you used for the bisect was, 7.10?
