Possible bugs in OpenCL drivers

Hi,

I have discovered several cases where programs compiled and executed on HD Graphics Haswell GT2 Desktop produce different output to on other OpenCL implementations. Please see attached bug reports, which provide additional details and steps to reproduce.

On Xeon-Phi, this kernel causes a segmentation fault during compilation:

Cheers,
Chris

No problem Jeffrey. In the cases where there's no error messages, I can't weed out obvious duplicates, so apologies if any of those reports are dupes.

Cheers,
Chris

Compilation of this 4 line kernel hangs the compiler on GT2: http://paste.ubuntu.com/25180351/

This 1 line kernel segfaults every Intel compiler we're tested, except an i5-4570: http://paste.ubuntu.com/25180582/
