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?
