--- Comment #6 from Mikael Morin <mikael at gcc dot gnu.org> ---
further reduced test below.
Fails with trunk-20130619 and 4.7.3 here.
And works with 4.8-20130416.



module matrix
  type :: sparse_matrix
    integer :: max_degree
  end type
end module

module bsr
  use matrix
  type, extends(sparse_matrix) :: bsr_matrix
  contains
    procedure :: get_neighbors
  end type
contains
  function get_neighbors (A)
    class(bsr_matrix), intent(in) :: A
    integer :: get_neighbors(A%max_degree)
  end function
end module

program main
  use matrix
  use bsr
end
