--- Comment #2 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks for the report, that does indeed look like a bug while compiling a shader.
Could you try if it also happens with Mesa master?
If yes, could you provide an apitrace?
If no, you could use `git bisect` to find the commit that fixed the bug.
