The gfortran code from a few months back had a number of crucial  
bugs, one or more of which is probably your problem.  The gfortran  
code in apple-gcc-5202 is the gcc-4.0.1 release version.  Your  
gfortran 4.1.0v20050517 code would probably have less bugs.

I think you could get even better code by waiting a few days for the  
gcc-4.0.2 release, which will have a lot of important bug fixes, and  
would be much more consistent with the officially released Apple  
gcc-5026.
