Description

Created attachment 125482 reduced sample of the crashing kernel

I have a program that segfaults reliably(always) when compiling the attached kernel and using beignet as OpenCL platform. The sample is part of a bigger kernel, of which I have stripped everything that is not necessary to provoke the crash. I actually have three different kernels that crash, that all have this pattern. Other Kernels compile fine. The Kernels compile and run with the Intel, AMD and nvidia platforms.

The hardware is Skylake ULX GT2. I built commit b55060c0 from the beignet repository with GCC6.1.1 and LLVM 3.8.0.
