Why does MATLAB 7.8 (R2009a) crash when I use SVD, CHOL, LU, EIG, or LEGEND?

MATLAB crashes when I use any commands that make use of LAPACK. This includes SVD, CHOL, LU, EIG, and even LEGEND. Here is an code snippet that crashes MATLAB:
legend('string1', 'location', 'best');

The crash is caused by an incompatibility between MATLAB and the CPU. This can happen if the processor does not support the SSE2 instruction set, for example, the Athlon XP 2200+ CPU.
As noted in the System Requirements page (URL below), the processor must support the SSE2 instruction set.
