I am using 2.95.3 with atlas 3.3.13. I'll upgrade my ATLAS overnight tonight.

You are right. The double version worked here also.

I'll try on the RH 7.1 system with a new ATLAS 3.3.14 install system tomorrow.
This doesn't sound like a wrapper problem though. It may be a bug in
ATLAS??? -- or just the permutations of tools we are using??? Either way,
hopefully there is fix for ATLAS that works across these tools. If all else
fails, we can put a test of cdotu in the code, and if it fails, disbale it for
