--- Comment #11 from Christopher Albert <albert at tugraz dot at> --- Created attachment 65180 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=65180&action=edit 0001-fortran-Preserve-host-association-for-dummy-procedur.patch Require a known procedure kind before a provisional subroutine attribute counts as a declaration. This preserves host association for the optional dummy procedure and avoids the undefined external symbol. A run test covers absent and present callbacks. check-fortran and the libgomp Fortran suites are clean.
