I think this problem is fixed with the current control package sources (from the hg archive). But one more fix is needed. The file src/control.cc should include control.h. I'll check in that change as soon as I can remember how to push a change to the hg archive on source forge...

What version of the control package are you using?

I think this change to the control package should help: http://hg.code.sf.net/p/octave/control/rev/bd6548d8d006

If you are already using that, then I can try to take a look.

With the default branch hg id
4890b1c4a6bd tip @

I get a wrong answer back from a call to the slicot library.
the
[a, b, c, d] = _sl_td04ad_ (ucoeff, dcoeff, index, tol);
line in file @tf/__sys2ss__.m
returns a wrong answer and octave stops.

stable hg id (64c0842f4e81) works ok

I think the problem is probably related to the recent changes to the integer sizes.
Any Ideas as to fixing or proving this hypothesis is welcome.
