There are several well known DJGPP effects that can cause this, if you can
sent me an example program (not the data, please! :-) I will take a look at
it, although I cannot promise when.

In the meantime, if you get this exception when the data file is larger then
256K, try using the 'stubedit' program on your executable to increase its
stack space (to, say, 512 Kb).
