Hi,

I already reported this when playing 1st time with my llvm-toolchain
v3.6.0rc2 and mesa v10.3.7 [1].
The issue still remains in mesa v10.4.4.

So, this is a field test to see if LLVM/Clang v3.6.0rc2 fits my needs.

I see the following build-error...

...

I have attached my build-script, the detailed full build-log (used
'clang -v' and 'make -j1') and the two diagnostic tmp-files.

I am not sure if this is fixable in mesa by refactoring the code -
that's why I CCed especially Jose.

If it's a llvm/clang bug, so the folks there should look.

If you need more informations, please let me know.

Thanks.
