Any ideas on the best way to deal with AI (illegal floating point operation) 
exceptions?  I can trap them, but then what?  For example, I set up a break 
point in a dummy exception handler, and I found 3 registers with NANs in 
them.  But how to know which register triggered the AI, as perhaps one or 
two of the registers were using integer rather than floating point (and thus 
did not contain NANs)?

Thanks,

Tom
