This is incorrect -- the code does not conform to F2003 either.  Section 9.11,
paragraph 3, says that a recursive I/O statement -- that is, one that occurs
while another is in progress, such as the "print *, 'test'" in this code -- 
may not identify an external unit, unless it is a "child I/O statement". 
Section 9.5.3.7.1, paragarph 2, defines a "child I/O statement" as one that's
occuring within a user-defined derived-type I/O function -- which is definitely
not applicable here.

Therefore, I believe that this bug should be closed as INVALID, but given the
amount of commentary (and the fact that hanging is an unfortunate response even
to invalid code), I'll let someone else make that call.
