I've gotten that same problem with the Amiga version *and* the windows
version of POV Ray.  I never could track down the cause so I eventually
concluded that it was a C pointer error and thus beyond ny control.  As a
workaround, I added this line near the beginning of the affected scene
file:

 #declare NaN = 0;

It's lame but it worked for me.
