--- Comment #5 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
Reduced testcase, still failing with -shared on darwin14:

module foo
contains

  subroutine bar
    use, intrinsic :: iso_c_binding
    call gee(c_funloc(gee))
  end subroutine

  subroutine gee(f)
    use, intrinsic :: iso_c_binding
    type(c_funptr) :: f
  end subroutine

end module foo

Fixed by r11-3302-g3696a50beeb73f . That is it was a front-end issue where the
location was not correct until then.
