Up to date Arch Linux, including: linux 4.18.12.arch1-1, xf86-video-amdgpu 18.1.0-1, mesa 18.2.2-1, opencl-mesa 18.2.2-1, xorg-server 1.20.1-1, and plasma-desktop 5.13.5-1.
(Recently installed system that STARTED with: linux 4.18.9.arch1-1, mesa 18.2.1-1, and opencl-mesa 18.2.1-1.)
I have not tried AMDGPU-PRO. (Not really interested anyway, and the Arch AUR package for it is 17.40, which requires downgrading to linux 4.9 and Xorg 1.18.)

Anything using OpenCL immediately segfaults.
Everything that segfaults runs just fine if I uninstall opencl-mesa, and either use opencl-amd (Arch linux package, which extracts OpenCL library from AMDGPU-PRO 18.30 but allows it to run with the open source AMDGPU driver.) Everthing also runs fine if I instead use intel-opencl-runtime to just run off the CPUs.
luxmark 3.1 crashes in pipe_radeonsi.so, called by libMesaOpenCL.so.1, called by libOpenCL.so.1.
A gdb backtrace with opencl-mesa 18.2.2 that I compiled in debug mode with symbols is attached or here: http://termbin.com/to7v
A gdb backtrace with opencl-mesa 18.2.2 (Arch binary, so without buildtype specified and no symbols) is here: http://termbin.com/m1yx
Setting environment variable MESA_DEBUG causes no additional output.
Granted, IndigoBenchmark_x64_v4.0.64 crashes by calling /usr/lib/libOpenCL.so::clGetPlatformIDs() which is ocl-icd, but without opencl-mesa and instead with opencl-amd, it runs through it just fine.
