Thanks for your report but, unfortunately, I cannot replicate this bug 
and I am hereby tagging this bug report accordingly.  I tried with octave 
4.0.0-3 in three different systems: a pure jessie (stable), an up-to-date 
unstable, and a mix of jessie+stretch.  I suspect that your problem has 
something to do with your specific system.

Could you please try to replicate it in other systems?
