Dear bug-octave:

Any attempt at defining a transfer function in Octave as installed
on my MacOS X (10.3.7) box caused a core dump.  This affects both
my interactive attempts and the demo.

octave:1> t = tf2sys(1, [1 3])
warning: in /sw/share/octave/2.1.53/m/control/system/__sysdefioname__.m near 
line 47, column 10:
warning: list objects are deprecated; use cell arrays instead
panic: Bus error -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Bus error

The possibility that I'm doing something wrong is high, as I'm an
Octive newbie.  However, I'm guessing that even improper input
shouldn't cause a core dump.  (The above is the same output displayed
when the transfer function definition sequence of the demo begins
executing commands, btw.)

I've tried re-installing and re-building and re-installing to avail.
Simple things work beautifully, including plotting through gnuplot.

Any ideas for a work around?

Thank you for your time.  I'm pretty impressed by what I've seen so
far of Octive.  It looks like an incredible program.

Thank you-
Mike Lusignan
