    While running the OpenBLAS test suite, `openblas_utest` built with clang-16.0.5 (and OpenMP support) hits this assertion and hangs the test suite:

```

This was originally reported by another Gentoo user (https://bugs.gentoo.org/910415), but I can reproduce it myself. I believe the source is in https://github.com/xianyi/OpenBLAS/blob/develop/utest/test_post_fork.c
