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. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?57234> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
