clinfo is https://github.com/Oblomov/clinfo at version: 2.2.18.04.06

Problem

I start gdb clinfo and type run. After spawning a couple of threads (and gdb seeing an exception being thrown and caught from Mesa Clover, s.b.) it outputs:

Otherwise (i.e. with respect to the exception and the segfault) the behaviour is the same in both orders.

Regression

I never got OpenCL to work on this system. Still working on it. :)

Extra information

I also see an exception being thrown from Mesa Clover, but that does not stop clinfo as it seems to be caught by Mesa: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3255/-/issues/3255

rocminfo also fails with an assertion: ROCm/ROCR-Runtime#97

Hi,
I have the exact same issue. Is there any workaround for this or we just have to wait for a fix ?
(on AMD Ryzen 7 1700X linux 5.8.5-gentoo on a Vega64 (Vega 10 XL/XT) Liquid cooled)
my gentoo tells me I have rocm comgr 3.7.0. does it include the patch referenced as closed ?

I would like to also add that after a ln -s trick to redirect /usr/lib/llvm/roc to /usr/lib/llvm/10 (essentially redirecting all attempt to reach llvm roc toward my system llvm10) it does avoid the crash but softwares like DaVinci Resolve or blender still can't use it. Not sure how that help but just in case...
Also might be interesting to note: I recompiled llvm-roc with debug flags and now instead of SEGV I get clinfo: /var/tmp/portage/sys-devel/llvm-roc-3.7.0-r1/work/llvm-project-rocm-3.7.0/llvm/include/llvm/Support/CommandLine.h:852: void llvm::cl::parser<DataType>::addLiteralOption(llvm::StringRef, const DT&, llvm::StringRef) [with DT = llvm::FunctionPass* (*)(); DataType = llvm::FunctionPass* (*)()]: Assertion 'findOption(Name) == Values.size() && "Option already exists!"' failed. right at the start.

I don't know if any current issues with clinfo. If anyone is still hitting errors with this please comment and I will reopen!
