  Target Milestone: ---

The following code (which must be in two files to trigger the error) causes=
 an
ICE using the latest gfortran.

$ cat ice1.F90
module iv
  type, public :: vs
   contains
     final :: destructor
  end type vs
contains
 elemental subroutine destructor(s)
    type(vs), intent(inout) :: s
  end subroutine destructor
end module iv

contains
  function en() result(dd)
    use :: iv

  end function en
end module d

module ni
contains
  subroutine iss()
    use :: d
    return
  end subroutine iss
end module ni
