Hi All,
I'm a novice Octave user running Octave on an old 486SX laptop
(Toshiba 1910CS) and am having the same issues mentioned in this older
email:
http://www.octave.org/octave-lists/archive/bug-octave.1998/msg00282.html
Any ideas on how I should go about debugging this? Here seems to be
the more pertinent parts of strace:
