When enabling the OpenCL use flag for Mesa, programs which use OpenCL, including clinfo and Blender, crash, with Valgrind and gdb showing a stacktrace with errors in libLLVM-13.so. I have also posted about this in the forums: https://forums.gentoo.org/viewtopic-t-1146321.html?sid=35bf01b96752e6b28ee3e13b0e0f0227. However, nobody has responded. Since even after updating to the latest Mesa 21.3.2 the issue persists, I have decided to file a bug. Reproducible: Always Steps to Reproduce: 1. Have mesa installed with the OpenCL use flag enabled. 2. Run any OpenCL program; my example is Clinfo as it is fast and easy to debug.

initially found this bug, Nvidia's OpenCL and ROCm were also installed and polluting the logs. However, even after uninstalling these, the issue still perists. I currently have sys-devel/llvm-roc installed because temporarily uninstalling it did not seem to change the result of the issue at all.
Created attachment 759863 [details] Some stack traces
It is sad to read that you have problems with the software. The situation seems to be a bit more complicate and requires some analysis. The forum was the right place, please try it there a bit longer until you can describe what is broken. Write the category and package name and version in the summary. We can not help you efficiently via bug tracker. The bug tracker aims rather on specific problems in .ebuilds and less on individual systems. I have had very good experience on the gentoo IRC [1] with questions like this. Of course there are also forums and mailing lists [2,3]. I hope you understand, that I will close the bug here therefore and wish you good luck on one of the mentioned channels [4]. Please reopen the ticket in order to provide an indication for an specific error in an ebuild or any gentoo related product.
