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.
