--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The standard says that skip_permission_denied means to ignore "an error
indicating that permission to access p is denied" and it's pretty clearly
intended to correspond to std::errc::permission_denied errors, not
std::errc::operation_not_permitted.
But this should solve the issue for MacOS:
