Confirmed, still present in the current version of the control package. Cc'ing control package maintainer.

The following code

results in the error

Although iddata also produces the warnings

+vebatim+
warning: iddata: more outputs than samples - matrice 'y' should probably be transposed
warning: iddata: more inputs than samples - matrice 'u' should probably be transposed
-verbatim-

I think that it would be better for n4sid to detect the situation and give a meaningful error message instead of calling IB01AD with an invalid input.

I'm using Octave 3.6.4 and octave-control 2.6.2-1 on a Debian system, but I don't see any changes in the current control package sources that look like they fix this problem.
