if it crashed right after you started calculation, then it's a bug
that I don't know. 

if it crashed after the sample broke, then it is a known bug. It is
related to drawing in OpenGL a rod that is being deleted at the same
time (because it breaks). This does not occur when you close the
OpenGL window.

I never got around to fix this bug, beucase synchronising threads
(display <-> calculation) is so complex. But also, this bug never
bothered me too much, because when some serious calculations are
being run, the OpenGL display is always off (no point to draw
calculations that takes few days, better to look at it after it's
finished).

There are few more simple FileGenerator examples in the code in
latest trunk, you might want to try the svn version and see it.
