Commen= t # 7 on bug 10200= 9 from Markus 
I tried to obtain debug information from Mesa but was unable t=
o do so (i.e.
starting Blender with `MESA_DEBUG=3Dcontext CYCLES_OPENCL_SPLIT_KERNEL_TEST=
=3D1
./blender` did not generate any visible debug information).

What I did instead, is run Blender via gdb which then gave the attached sta=
ck
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.
