Hello.
I encountered several clang crashes when compiling with OpenMP enabled and instrumenting for MC/DC coverage, all of them are encountered when trying to `compile pragma omp parallel` regions.
Minimal reproducer with most of non-relevant flags stripped: https://godbolt.org/z/zzY1GacWM. It reproduces on Clang 21.1.0, 20.1.0, 19.1.0.
I am not completely sure if `-m64 -O3 -fexceptions` actually matter, crash is reproduced without them.
