Yeah, I turn on FP exceptions in one of my own apps, I've have had a lot
of problems with it.

I've gotten it to be reasonably stable by making sure exceptions are
only turned on during a period when my own code is in control (meaning
no external library calls), and making sure _all_ my code is compiled
with options that tell the compiler what's up (-ftrapping-math).

However it certainly doesn't sound like the borland/delphi code is being
so careful...

[Exceptions do help immensely in debugging subtle FP problems though.]
