Chris. First note that this problem is NOT the problem documented
above. The problem documented above is due to a bug in the IBM
compilers.  The only suggestion I have with your PGI compiler
problem is to make sure you have the latest stable compiler.
We are using pgf90, and pgcc 3.3-2, and don't run into this
problem. On a different machine we have pgf90 3.2-3, and don't
have this problem either. As such I suspect this isn't a code
problem as much as a compiler bug with a specific release of
the Portland group compiler.

As one suggestion you may be able to get it to work with your
current compiler, by compiling history in DEBUG mode (or with
less optimization) and everything else in production mode.


Good luck...
