Yes, it doesn't crash anymore, thanks!

There are still other bugs that prevent it from running, and as I understand
most renderer features are disabled with default flags/defines under Mesa...
>>From https://developer.blender.org/T41912 - "Note though: Building without SVM

The first bug is about libclc - it incorrectly references fabsf() in R600
bytecode files, while it should probably use llvm.fabs.f32()... Where to report
it?

Second, it seems Blender developers are using half-precision floats
(vstore_half4 function)... it's used in only one place and I don't know if its
usage is really critical, but it of course prevents the kernel from
compiling... I've reported it here https://developer.blender.org/T42813
