CodeWarrior v6.1 interrupt handling

I just upgraded a project designed under CodeWarrior for the MCF5485 
Coldfire chip from v5.6 to v6.1. Everything works fine except that the 
interrupt handlers all return with an exception error. The exception stack

shows that the error is a FORMAT error. (code=0x0e). I noticed that the
new 
version places a FSAVE and FRESTORE instruction in the handler. The old 
version did not. I'm wondering if this is causing the exception, or if 
anyone else has had this problem.

Thanks!
