[Bug 102009] Blender crashes when compiling OpenCL kernel

https://bugs.freedesktop.org/show_bug.cgi?id=102009

--- Comment #7 from Markus mw@graph-ix.net --- I tried to obtain debug information from Mesa but was unable to do so (i.e. starting Blender with `MESA_DEBUG=context CYCLES_OPENCL_SPLIT_KERNEL_TEST=1 ./blender` did not generate any visible debug information).

What I did instead, is run Blender via gdb which then gave the attached stack trace at the time of crash. Looking at the trace, it appears like the crash is inside LLVM.

What is the best way to debug this further?

P.S.: As I just updated to Ubuntu 17.10 (Beta 2), I've also attached new glxinfo and clinfo output.
