I'm unable to reproduce this. There was a similar problem reported in
February 1999. I don't remember the exact resolution, except that I
don't think it was a bug in Octave.

Hmm. It looks like you are using g77 and g++ from egs 1.0.3, but gcc
is 2.7.2.3. It might be a good idea to use the compilers from gcc
2.95.x instead of some old egcs version, and to not mix them up with
an older version of gcc.
