lighting.c and render.c are both from June 10.
My trace says its crashing from Reflect() calling Trace() 
which calls Determine_Apparent_Colour(),
and for some damn reason on the line call to Normal() 
(Triangle_Normal()) which is just a memcpy from and to
a couple of perfectly fine addresses.

Could there be something just so offensive about a 
particular spot (and view of that spot) on a triangle 
that POV acts like this?
