Indeed. I expected compilers to treat the program as either bad f95 or 
good f2003, because we're still in the transition period between them
9 years after 2003. So I was happy for gfortran 4.4.4 to treat it as
good f2003 but not for 4.6.2 to crash at compile time.

IMHO the wisdom of J3 is HUGE but not INF :-)
