Clang asked to attach these files to the bug report
Compiling the code in the attachment, I get a clang-internal error:
FYI: after the discussion in bug report 40707, I replaced all global / local /
constant / private in the libclc headers with __global, __local, ...
Below is the clang error message:

gpu_mem, __global AliGPUConstantMem* pConstant, int iSlice)
