I am using MSC to write a macro interface to Harvard Graphics - no
big deal.  The problem however is that when I execute my code I get
different results from the same data each time it is run.  Sometimes
the program works as I expect and sometimes it crashes the machine.
Removing printf debug statments also seems to affect the outcome.

I talked with MS and they said to recompile the program disabling
all optimizations.  When I do that, the programs doesn't work at all.

Does anyone have any suggestions as to what to look for - I'm one
lost sole on this one.
