This wrong, there are several tests;-) The one that is missing is of the form:


module psb_base_mat_mod
  type  :: psb_base_sparse_mat
    integer, private     :: m, n
    integer, private     :: state, duplicate 
    logical, private     :: triangle, unitd, upper, sorted
  end type psb_base_sparse_mat
end module psb_base_mat_mod

module psb_d_base_mat_mod
  use psb_base_mat_mod
  integer, parameter  :: psb_dpk_ = kind(1.d0)
  type, extends(psb_base_sparse_mat) :: psb_d_base_sparse_mat
  end type psb_d_base_sparse_mat

  type, extends(psb_d_base_sparse_mat) :: psb_d_coo_sparse_mat
    integer              :: nnz
    integer, allocatable :: ia(:), ja(:)
    real(psb_dpk_), allocatable :: val(:)
  end type psb_d_coo_sparse_mat

end module psb_d_base_mat_mod

module psb_d_mat_mod
  use psb_d_base_mat_mod
  type :: psb_d_sparse_mat
    class(psb_d_base_sparse_mat), allocatable  :: a 
  contains
    procedure, pass(a) :: d_csclip
    generic, public    :: csclip =>  d_csclip
  end type psb_d_sparse_mat

contains 

  subroutine d_csclip(a,b,info)
    use psb_d_base_mat_mod
    implicit none

    class(psb_d_sparse_mat), intent(in) :: a
    class(psb_d_sparse_mat), intent(out) :: b
    integer,intent(out)                  :: info
    type(psb_d_coo_sparse_mat), allocatable  :: acoo

    info = 0
    allocate(acoo,stat=info)    
    if (info == 0) call move_alloc(acoo,b%a)

  end subroutine d_csclip

end module psb_d_mat_mod
