        * class.c (has_finalizer_component): Prevent infinite recursion
        through this function if the derived type and that of its
        component are the same.
        * trans-types.c (gfc_get_derived_type): Do the same for proc
        pointers by ignoring the explicit interface for the component.

        * check.c (same_type_check): If either of the expressions is
        BT_PROCEDURE, use the typespec from the symbol, rather than the
        expression.
