I am using version 2.3, and considering buying 2.4 on a 286.  I spent
the better part of this evening trying to isolate a bizarre situation
whereby a double panics the system.  Using sdb, the system panics on 
apparently innocent statements like:

	if (dbl < 0.0)
		someint = 1;

Can anyone shed any light on the nature of this problem?  For the most
part, I find our code compiles flawlessly, but then again we have to
be very conservative to keep all other destination machines happy.


TIA,

P.S. a 80287 is installed, but I have experienced similar problems before
we bought the chip.
