Unfontunately, this has been true for a while.  I've known about it, but it just doesn't happen that frequently.  For that reason, I've lowered the priority.

In the meantime, I would use 'dbcont' to escape debugging without triggering the abort call.

I can confirm the bug, even using FLTK in single threaded (--no-gui-libs). Here is a simplified test, using the attached tst_fun.m callback:


function retval = tst_fun (h, ~)
  keyboard
  disp (get (h, "type"))
endfunction


Run the the following at the prompt:


octave:1> uimenu ("label", "toto", "callback", @tst_fun); ## Click the menu
octave:2> stopped in tst_fun at line 2 [/foo/bar/tst_fun.m]
2:   keyboard
keyboard> dbquit
terminate called after throwing an instance of 'octave::quit_debug_exception'
fatal: caught signal Abandon -- stopping myself...
## Press the button


I attached the single threaded back trace.

If I debug a .m file with GUI elements Octave always crashes if I click on "Quit Debug Mode" in callback.

Reproduce

  • open attached ui_demo.m
  • set breakpoint to line 152
  • run ui_demo
  • in demo window click on "blue" radio button -> breakpoint hits
  • stop debugging by clicking on "Quit Debug Mode"

-> Octave crashes

This does not happen with Octave 5.2
