…dummy We presently allow a NULL() actual argument to associate with a non-optional dummy allocatable argument only under INTENT(IN). This is too strict, as it precludes the case of a dummy argument with default intent. Continue to require that the actual argument be definable under INTENT(OUT) and INTENT(IN OUT), and (contra XLF) interpret NULL() as being an expression, not a definable variable, even when it is given an allocatable MOLD.
