Hi John,
I compiled the latest octave 3.1.51+ in the following manner:

./configure --prefix=/usr  F77=gfortran
instead of g77 and everything works fine.
Thanks
Riccardo

I suspect a build or configuration problem. If you want help
debugging this problem, then I'd suggest treating the problem as a bug
report and providing more information. Please read
http://www.octave.org/bugs.html to see what information might be
relevant to include in your report.

But if you think there is a bug in Octave and you'd like to try
debugging where the crash happens, then the thing to do is extract the
tests from the qr.cc file, start Octave with

./run-octave -g

type "run" at the (gdb) prompt, and then run the tests. When the
crash happens, you can find out where and what values are involved.
People here who aren't seeing the crash can't do this for you.

Also, if you are using the latest version of Octave (either 3.1.x or
from the Mercurial archive) then I think it would be best to join the
maintainers list and discuss problems with the development version of
Octave there rather than on the help list.
