Default User function bug?

I'm using CFX13, and what I'm essentially doing is applying an algebraic intermittency function via user fortran.
I've checked my function extensively, but something odd happens that I can't explain, I run CFX with my function and it gives me an invalid operand error, suggesting a negative sqrt or so. In order to debug the issue, I put out write statements, to see what is causing this. Once i have a write statement (to a file) in the do loop everything works. No write statement, crash with the operand message. Write statement all is good, obviously it runs slower though.
Any ideas? Or is this a bug?
