I can't reproduce this problem on a Linux system with

  * Linux kernel 2.0.6
  * gcc/g++ 2.7.2
  * g77 0.5.18
  * libg++/libstdc++ 2.7.1.0
  * libm 5.0.5
  * libc 5.2.18
  * libncurses 3.0
  * ld.so 1.7.14
  * binutils 2.6

I suspect that you have some library version mismatch.  Pretty much
all I know about this kind of problem is in the file

  ftp://ftp.che.wisc.edu/octave/README.Linux

Please note that I am NOT recommending that everyone running Linux and
using Octave should install the same versions of the libraries and
compilers that I have.  I am simply saying that the versions listed
above work for me.  Other version combinations may also work, but I
don't have time to map out all the possibilities...
