Thanks for the report. Note that you are using a very outdated version of control (2.3.52), the current version is control 2.6.0. IIRC, this bug has been fixed in control 2.3.53 (hg revision 774). Could you please double-check the current version in the link below if that is the case?

The function doesn't correctly perform the check on the system blocks dimensions (see function documentation before proceeding).
The check should make sure that the 'feedout' indeces don't exceed the dimension of the output of 'sys1', namely the forward block for the feedback function. Instead, the function performs that check on the local variable 'feedin'.

What the function DOES:
/usr/share/octave/packages/control-2.3.52/@lti/feedback.m:line 131

What the function SHOULD DO:
/usr/share/octave/packages/control-2.3.52/@lti/feedback.m:line 131
