[Octave-bug-tracker] [bug #57234] 'dbquit' in graphics system callback function can cause segfault

[John W. Eaton]

Follow-up Comment #10, bug #57234 (project octave):

Here's another way to demonstrate the problem.  Define the following function
(can be at the command line):


function fff ()
  remove_input_event_hook ("fff");
  error ("foobar!");
endfunction


then execute


debug_on_error (true);
add_input_event_hook ("fff");


that should put you at a debug prompt.  Then enter a dbquit command and Octave
will crash with


terminate called after throwing an instance of 'octave::quit_debug_exception'


I'm working on a fix so that quit_debug_exception is handled properly when it
is thrown from a function that is executed in the readline event loop.
