[Octave-bug-tracker] [bug #34605] isequal fails on diagonal matrix

[Steve Duncan]

Follow-up Comment #5, bug #34605 (project octave):

It's happened again.  This time I did "clear all" and the problem still
persists:

Note that this time I am in the debug prompt, where I have put a keyboard
statement in a script.

The history before this:
