It can also be due to system and compiler differences - the compiler
optimization can have very different numerical effects, especially in
stochastic methods. Many of our regression tests are tuned to run on
a specific machine, which is unfortunate but we have no way otherwise
to check if the actual answer matches what's expected (as opposed to
merely checking if the program runs without crashing).
