Summary: Application fails assertion when compiled with
optimizations

Source code which triggers the bug
I have run into a problem where my application will fail assertions when
compiled with optimizations that it would pass when compiled without them. The
code compiles without any warnings or errors.
I am running Ubuntu 10.10 (AMD64) on an Intel Core 2 Duo P8600. I am compiling
the code with "-Wall -Werror -std=c99".
The code I have attached is the full source to my raytracer, and I have coded
in a scene which renders quickly (<5 seconds) and triggers the bug when
compiled with optimizations. The executable produced takes no arguments and
produces a output bitmap image.
Note, the makefile included in the attached source is set to build without
optimizations, so the code produced initially should run successfully to
completion.
