Code to reproduce:


octave:2> r = audiorecorder ();
octave:3> r2 = r;
octave:4> isequal (r, r2)
error: isequal: Impossible to reach code.  File a bug report.
error: called from
    isequal at line 182 column 9
    isequal at line 137 column 18


Per Octave's instructions, I'm filing a bug report.

Note that new-style classdef objects do work.


octave:7> m = containers.Map ();
octave:8> m2 = m;
octave:9> isequal (m, m2)
ans = 1


Apparently this has been present for a very long time because I went and tried
Octave-4.4.1 and it has the same error.
