--- Comment #2 from anlauf at gcc dot gnu.org ---
OK, here's a better example of the weird situation:

program p
  call s()
  call s(i=3D7)
  call s(c=3D'a')
  call s(r=3D3.0)
contains
  subroutine s (i,c,r)
    integer  , value, optional :: i
    character, value, optional :: c
    real     , value, optional :: r
    print *, "present (i), present (r) =3D", present (i), present (r)
  end subroutine s
end

With 12-branch this prints:

 present (i), present (r) =3D F F
 present (i), present (r) =3D T F
 present (i), present (r) =3D F F  ! right but for the wrong reason...
 present (i), present (r) =3D F F  ! should be F T

With 13-mainline + patch under review for pr107441(v2) I get:

 present (i), present (r) =3D F F
 present (i), present (r) =3D T F
 present (i), present (r) =3D F T  ! should be F F
 present (i), present (r) =3D F T  ! right but for the wrong reason...

So not a regression... ;-)=
