I can't seem to reproduce this problem using Octave 2.0.15 or the
current development sources on a system running Linux, or with 2.0.15
on a system running Digital Unix.

What version of Octave are you using, and on what kind of system?

BTW, if you think you've found a bug in Octave, it is better to submit
a complete bug report to the bug-octave mailing list.

Thanks,
