I was getting a somewhat anomalous error message from c++ so I built
a short test file to find out what I was doing wrong.  Imagine my surprize
when the file caused cfront to dump core.  Imagine my shock when 
I found out that the core that was dumped was in an improper format for
dbx to parse.  This makes life a bit difficult.  I include the file that
dumps the core.  This may not be correct c++.  However dumping core is
not the way to notify me of this fact.
