On an ~AMD64 system with an Intel Tiger Lake Xe GPU when I attempt to run clinfo (from https://github.com/Oblomov/clinfo) I get a segfault as per: Thread 1 "clinfo" received signal SIGSEGV, Segmentation fault. 0x00007fffe2b1d461 in llvm::PointerType::get(llvm::Type*, unsigned int) () from /usr/lib/llvm/13/lib64/libLLVM-13.so (gdb) bt #0 0x00007fffe2b1d461 in llvm::PointerType::get(llvm::Type*, unsigned int) () from /usr/lib/llvm/13/lib64/libLLVM-13.so #1 0x00007fffc8db1535 in ??

Unfortunately, even with USE="debug" the library is stripped so I can not get symbols. This GPU has worked fine in the past with previous releases (although I am unsure how far back). Is it certainly the case that intel-graphics-compiler supports LLVM 13? $ emerge --info Portage 3.0.30 (python 3.9.12-final-0, default/linux/amd64/17.1/desktop/plasma, gcc-11.2.1, glibc-2.35-r2,

Did you tried back older dev-util/intel-graphics-compiler-1.0.10778-r1 and dev-util/intel-graphics-compiler-1.0.10713-r1? Does it also segfault here? My GPU is older, as I have only Skylake, but I don't have segfaults here.
I can confirm these issues on the older releases. Same place. Has anyone with a recent Intel GPU had success? Last time I can confirm it was working was back in December.
*** Bug 840939 has been marked as a duplicate of this bug. ***
@Jan: I did run a local test with LLVM-12 and indeed the segfaults with clinfo are gone. @mgorny: How long do we will have LLVM-12 in tree until removal?

I just bumped to newest compute-runtime and added a test for LLVM-12. I tested on multiple systems and clinfo didn't segfault anymore. Could anyone also test and report?
