Tobias,

here's another case where it crashes again:

% cat gfcbug127.f90
module gfcbug127
  implicit none
  type t
     integer :: grid = 0
  end type t
contains
  subroutine read_nml (nnml, s)
    integer, intent(in)  :: nnml
    type(t), intent(out) :: s
    integer              :: grid
    call read_nml_type_2
    s% grid = grid
  contains
    subroutine read_nml_type_2
      namelist /N/ grid
      read (nnml, nml=N)
    end subroutine read_nml_type_2
  end subroutine read_nml
end module gfcbug127

% /opt/gcc/4.9/bin/gfortran -c gfcbug127.f90 -g
gfcbug127.f90: In function 'read_nml_type_2':
gfcbug127.f90:17:0: internal compiler error: in force_decl_die, at
dwarf2out.c:20111
     end subroutine read_nml_type_2
