--- Comment #81 from Jonathan Wakely <redi at gcc dot gnu.org> --- Basically we think there's a bug in the APFS filesystem, nobody can reproduce it on other systems, none of us have access to such a system. It would be really helpful if somebody seeing the error could investigate and tell us more than "it still fails for me".
