Could be sorry. I think seeing the test it checks whether one of the two happens. Either an error is returned or an abort is seen.

> My changes let assert() abort the program, and abortion is taken as success.

I do not think that's the case. For example you skip the Additional data misuse in GCM ciphers, thus abort or error is not caught in that case.

> So the functionality of the test has not changed - it just doesn't rely on SIGABRT signal handlers. I could add a check `WIFSIGNALED(status) && WTERMSIG(status) == SIGABRT` to make 100% sure that not anything else caused program abortion, if that is what you are missing.

Ok, now I see that you rely on the fact that `check_wait_status()` does not fail on abort signal. I cannot think why `_check_wait_status()` would treat ABRT as success, and it may just be broken (thus you have uncovered a bug).
