This was the exact problem.  The machine that OpenCV crashed on was using an
Athlon processor.  The odd thing is that I built OpenCV on that same machine
but it didn't change the configuration or acknowledge the lack of SSE.

I changed the configure options to remove SSE support, recompiled, and now
everything works as expected.
