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.
