mesa-opencl-icd supports so far only OpenCL 1.1 and is also affected
by this bug.
amd-clinfo and clinfo from https://github.com/Oblomov/clinfo work fine.
As mentioned above removing the query CL_DEVICE_BUILT_IN_KERNELS fixed
the crash.
I've attached a patch to fix clinfo for OpenCL 1.1 drivers.
Please apply this patch.
Thanks,
Andreas.
