This seems to be allowed, see 12.5.2.7: If the dummy argument does not have INTENT (IN), the actual argument shall be a pointer. Otherwise, the actual argument shall be a pointer or a valid target for the dummy pointer in a pointer assignment statement. Only the target attribute is required, and a(:,2) has the target attribute. The program is properly rejected with -std=f2003. So this is probably a plain wrong-code bug.
