[Octave-bug-tracker] [bug #48519] Segfault with Qt plotting when running demos

[Pantxo Diribarne]

Update of bug #48519 (project octave):

                  Status:             In Progress => Patch Submitted

Follow-up Comment #29:

With those additional information, I can reproduce the crash. The issue is
that we are passing Figure objects member functions as callbacks to be
executed in the interpreter event queue. At the time the callback is executed,
the Figure object may not exist anymore, hence the crash. Note that this is in
fact the same origin as bug #54187.

I attached a preliminary cset (complicated I admit) that avoids passing such
dangerous callback, and fixes the issue for me. It does not fix bug #54187.

(file #45844)
