Loading and unloading Floating Point NaNs (Not a Numbers) is often the
source of such problems.  I'd look for something like that.
They can displays as: (Inf, Ind, NaN, SNaN, QNaN) w/ or w/o a sign.
Depending on your runtimes, processor, OS, and sometimes program history
(flag manipulation), you can get these values in different ways.
