I looked for the core dump, but could not find one...

I know the SW is old, but it is the only binary available for 
Win32...  I have tried to get cygwin to work on this pc (works 
computer so I have limited controll over what I can do to it), but I 
just have been able to get it up and running as of yet.

I will try the script on my Linux box at home running the latest 
version of octave and see if it still crashes..
