Ben I was able to confirm that the 3 changes made above did NOT conclusively
solve the problem. Unfortuantely the problem isn't consistently reproducible
so I am not sure anything I could package up would be useful. I have run
this analysis on several different computers. My desk machine, a Thinkpad
A61, always works. The two lap computers HP Desktops (not super machine but
competent and as fast as my laptop)  fail on a frequent enough basis that I
have to  come up with a solution.

Basically I have a script that performs an analysis on an image and
generates 2 plots. If I analyze 50 images, one after and other, Octave will
hang on 1 or 2 of the images. Unfortuantely it isn't the image itself that
causes the problem as it will be analyzed successfully one time, only to
fail the next time I analyze the image.

In  my review of the information associated with this commonly reported
problem, it seems to be a timing issue. 

I realize you can't help much if you can't reproduce the error. I will try
to look tonight to see if I can simplify the .m file and produce the error I
am seeing.
