gfortran 4.3.2 running out of memory on a file (with attached reproducer)

[Tom Epperly <tepperly at llnl dot gov>]

I've got a situation where gfortran is running out of memory, and I am 
wondering if there are any guidelines that would help me change my 
source file to get it compiling. I am working with code produced by 
source code generators, Babel http://www.llnl.gov/CASC/components/ and 
Forthon. I am attaching a reproducer.

$ sh compile
