As for why it works on 64-bit and Linux, they don't use the FPU there. So
essentially the pow() function is returning a double in a XMM register.

So if you run the above code I posted with -m64, it does a check using the FPU.
Which causes the assert to fail, cause of course it is now testing a double
(from pow()) and a real.

The whole situation is really messed up and it seems that it is flip flopping
between double and real cause in new hardware nothing actually supports 80-bit
floats it's dead. 

Really real should mean 128-bit float, it is the next logical step over 80-bit
floats.
