Get a copy of memtest86 (if you have an Ubuntu CD handy, just boot from that
and there's an option to start it). That will do a thorough test of your RAM,
if you're worried about hardware problems.

Are you using any DirectX code as part of your program, by any chance? There's
a DirectX bug (well, more of a designed in misfeature) that leaves the FPU in
the wrong mode, which causes Lua's fast truncate-to-int code to produce
incorrect results.
