When built against libc++ clinfo will SIGABRT. I reset my system to use LLVM 18 as the system wide compiler and libraries to avoid the std::char_traits<unsigned char>' deprecation. Tested against a vanilla intel-compute-runtime and dependencies, built with unset CFLAGS, CXXFLAGS, and LDFLAGS. Building against libstdc++ resolves the problem. Not a true fix but I can't think of anything that uses it as a build dependency. Reproducible: Always Steps to Reproduce: 1. Use LLVM profile with version 18 as the system toolchain to avoid build failures 2. Compile intel-compute-runtime 3. run clinfo Actual Results: Abort was called at 135 line in file:

(In reply to unhappy-ending from comment #0) The backtrace isn't very useful, unfortunately. Please build intel-compute-runtime at least with debugging symbols: https://wiki.gentoo.org/wiki/Debugging. Anyway, the assertion is at https://github.com/intel/compute-runtime/blob/fd2a073fc61299b856a83afd049a5428037f2844/shared/source/utilities/reference_tracked_object.h#L135. I don't have any other analysis.

No problem, I wasn't expecting any analysis. The error was included as a proof of sigabrt more than for actual debugging purposes. In the near future I'll give a debug symbol build a try and update after.
I have experienced similar crashes with rusticl. I might be caused by multiple versions of the same LLVM libararies loaded into the same process (icr loads LLVM 15, clinfo loads LLVM 18) which leads to multiple definitions of the same symbols. As upstream is lagging behind on porting to newer LLVM versions, there is not much we can do about that.
