Here is one sequence (all interruptions of the dots caused by me hitting

This is on 2xAthlonMP, 1 GB, Fedora Core 3, glibc-2.3.3, kernel-2.6.9-1.667, 
gcc-3.4.2-6.fc3,
octave-2.1.62.
Similar results on AthlonXP/ 500 MB (same software).
I am running it as we speak on 2xPPro 200 MHz w/ RH9 
(kernel-2.4.20-35.9.legacy, glibc-2.3.2,
gcc-3.2.2, octave-2.1.57) and it does not show any problems either.
It does show problems on Sparc Solaris 8 (octave-2.1.59, gcc-3.3.3)

It rather random half way through the running output:

4 2   4400     86560octave>

(I made up the numbers here)

I did not save the output and I could not get it to crash anymore...
