	PR fortran/68196
	* 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.

	PR fortran/66465
	* check.c (same_type_check): If either of the expressions is
	BT_PROCEDURE, use the typespec from the symbol, rather than the
	expression.
