Subject: Octave segmentation fault

Bug report for Octave 1.93 configured for i486-unknown-linux

Description:
-----------

Octave segfaults before reaching the octave prompt.  Re-creating
the file ~/.octave_hist seems to solve the problem and octave
gets a little further.  However:

analogue:~>octave

octave:1> history
Segmentation fault
analogue:~>ls -las ~/.octave_hist
   1 -rw-r--r--   1 jay      jay            60 Dec  5 17:06 /home/jay/.octave_hist
analogue:~>cat ~/.octave_hist
exit
exit
exit
exit
exit
exit

exit                    

Here is another example session:

octave:1> exit

octave:5> 2*3
Segmentation fault
analogue:~>cat .octave_hist
exit                          

Not much is working :(

Repeat-By:
---------

I can't get octave to do anything :(
But am willing to test out anybody's ideas ...

Fix:
---

:?

I can't reproduce these problems.  As far as I can tell, Octave works
fine on my Linux system.  I'm using

  i586, Linux 2.0.0, gcc 2.7.2, libg++ 2.7.14, and libc 5.2.18

What versions of libg++ and libc do you have?
(Run ldd /your/path/to/octave to find out).
