--- Comment #8 from anlauf at gcc dot gnu.org ---
Further reduced:

module mo_a
  implicit none
  type t_b
  contains
    procedure :: unpackbytes =3D> b_unpackbytes=20=20
  end type t_b
contains
  function b_unpackbytes (me) result (res)
    class(t_b), intent(inout) :: me
    character                 :: res(1)
  end function b_unpackbytes
  subroutine b_unpackint (me)
    class(t_b), intent(inout) :: me
!   print *, b_unpackbytes (me) ! ok
    print *, me% unpackbytes () ! ICE
  end subroutine b_unpackint
end module mo_a


The "arrayness" of the result res seems to be key.=
