[Bug fortran/41585] New: [OOP] Reject CLASS(T) as component of "TYPE :: T"

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

type t
  integer :: i
  class(t), allocatable :: foo
end type t

In Fortran 2003 this is invalid to have CLASS(T) in the same TYPE as the one
being defined. I think Fortran 2008 allows this, but as currently, deallocating
also does not work, I would simply reject it.


C438 (R440) If the POINTER attribute is not specified for a component, the
declaration-type-spec in the component-def-stmt shall be CLASS(*) or shall
specify an intrinsic type or a previously defined derived type.

C439 (R440) If the POINTER attribute is specified for a component, the
declaration-type-spec in the component-def-stmt shall be CLASS(*) or shall
specify an intrinsic type or any accessible derived type including the type
being defined.
