Rich,

I'm using a solaris box running SunOS 5.9.  I tried it on our Tru64 system
and got the same results that you did. I found the place where the
Floating Point exception happens but I didn't figure out why. The gribdump
program also had the same Floating Point exception.  The problem is in the
main code base.

I didn't have a full understanding of rotated lon/lat grids until I talked
with my co-workers. Now I can probably code the the creation of the
lat/lon part of the cdl.
