The program that is being used is by one of our developers and it
is using recursion internally to do smog particle simulation over
many frames (visual effects). Or systems are installed with
2GB of memory and they set there stack size to 128MB (from 64MB).
The program could write its data out to disk, but then the
performance gets killed.
We also had to knock up the stack size on the linux systems that
these programs are actually developed on.
