Yes, you are right. I think the message is not printed because the build fails
before that check - register count is checked when the shader is built, to get
the exact number with additional temporary registers etc. We can do additional
check before the build, to catch more problematic cases, but on the other hand
we have the error message anyway, though not so descriptive, and broken shader
code won't be used on gpu - so there are no lockups.

I doubt that non-LLVM shader backend will be able to handle that shader anytime
soon. LLVM backend currently can't handle it due to another problem, but it's
going to be fixed.
