This has got me worried because my workstation has the OpenCL from the AMDGPU-PRO version installed (but nothing else from it) and I'm using the open source amdgpu driver package. My reading of the bug analyses done by the devs (https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime/issues/103), is that I shouldn't be seeing the problem as it only affects the open source OpenCL package running with the open source amdgpu driver. Have I got this right? Is it possible I'm somehow using the open source OpenCL instead of the PRO? The output from darktable and inxi are below - do the experts know if this proves what I'm running?
darktable -d opencl:

Do you know if this is a realistic option for a non-dev user?If this is a problem with the open source ROCm OpenCL library, you can run open source amdgpu (present in Linux kernel) with OpenCL from AMDGPU-PRO.Here is for Ubuntu, but might be adaptable to others: https://math.dartmouth.edu/~sarunas/amdgpu.html

I everyday use amdgpu drivers, but when I use darktable, I use the proprietary amdgpu-pro OpenCL drivers. Here is my procedure:
Just download the drivers for the distro that is more similar to yours (example, RPM or Deb packages).
The example will follow RPM architecture, but for Debs the procedure is almost the same.
Unpack the tar.xz file in a folder let's call it
/home/user/unpacked
After that, you will have folder
/home/user/unpacked/amdgpu-pro
that contains subfolders
amdgpu-pro-install repodata RPMS SRPMS
go in RPMS and take all RPM files that are in subfolder
/home/user/unpacked/amdgpu-pro/x86_64
and put them together someelsewhere, for example
/home/user/amd_opencl
then unpack them all.
You will get
/home/user/amd_opencl/etc/
/home/user/amd_opencl/lib/
/home/user/amd_opencl/opt/
/home/user/amd_opencl/usr/
Then to run darktable
OPENCL_VENDOR_PATH=/home/user/amd_opencl/etc/OpenCL/vendors/ LD_LIBRARY_PATH=/home/user/amd_opencl/opt/amdgpu-pro/lib64/ darktable
