Unforutnately hmmer was not working for a > while, so there is relatively big interval about when this can happen. So looking into the reasons why it was failing is because the default C level changed to C23. So the spec config changed to include -std=gnu17 now rather than GCC being broken. So in theory someone could do a bisection with a decent spec config.
