This crash was produced on Frontier (HPE Cray EX supercomputer) with Clang 17.0.0 and ROCm 5.7.0. The crash occurs when compiling with -O3 -Ofast, but not with -O3 alone. I have also tested with Clang 15.0.0 and ROCm 5.3.0 where the issue does not occur. The reproducer scripts are attached. I'm sorry I was not able to get creduce to work on this system, so the reproducer has not been reduced.
