TIL: calling munmap() with wrong parameters can cause really strange occasional crashes in #AddressSanitizer or #Valgrind. Wrong parameters meaning in this case:
- passing wrong (too large) size,
- passing NULL,
- calling munmap() multiple times for the same pointer.Debugging the crashes was painful. What helped in the end was "doing the boring right thing": adding error checking to all related system calls, adding debug logs, fixing code smells.
