	We just upgraded to 3003 recently, and came across this
rather neat bug/feature of the FORTRAN compiler, where when a program 
is compiled with the optimizer turned on, the compiler merrily
"skips" over entire sections of code.  It looks like DO loops are
the most likely candidates for being skipped over.  I've not been able
to track the specifics down yet (very large source).

Has anyone seen this, and do you know what it is

Oh, B.T.W., compiling without the optimizer works fine...

Frustrated and Frantic...
