I see this has been addressed in the dev sources:

https://sourceforge.net/p/octave/control/ci/bd6548d8d0068e99f3f312658137397f298187fb/

(essentially by changing var type from octave_idx_type to F77_INT)

I looked at some other files in control package and sometimes info is initialized and sometimes it is not. The code needs some clean up.

I think the problem is that "octave_idx_type" has changed.
In sl_td04ad.cc ( around line 154) one can see:

"info" in TD04AD is integer, and "info" in sl_td04ad.cc
is octave_idx_type is long int (?), so it contains some trailing garbage. The quick (and, most likely, improper) fix is to
initialize info to 0L in sl_td04ad.cc.

In version 4.2.1, the two plots are shown, in the development version that's not the case.
