In particular Fortran 77 doesn’t have POINTER, but Fortran 77 can call C functions (though not in a standard defined way). It is probably uncommon that this case happens on automatic variables. I‘m unsure if we can do better than ignoring the problem or not set any fnspec for all functions for legacy/f77 standard programs? > > -- > You are receiving this mail because: > You are on the CC list for the bug.
