[Octave-bug-tracker] [bug #47699] FLTK can segfault after using legend

[Juan Pablo Carbajal]

Follow-up Comment #15, bug #47699 (project octave):

I think the following is related to this bug.


octave --no-gui --no-history --silent --eval "close_test"
error: base_graphics_object::get_properties: invalid graphics object
error: unhandled execution exception -- eval failed
octave-gui: ../default/libinterp/corefcn/graphics.cc:2725: void
gh_manager::do_close_all_figures(): Assertion `hlist.numel () == 0' failed.
panic: Aborted -- stopping myself...
Aborted (core dumped)


or

octave-gui:1> close_test
error: base_graphics_object::get_properties: invalid graphics object
error: called from
    delete at line 60 column 5
    closereq at line 42 column 5
    close at line 96 column 5
    test at line 5 column 1
octave-gui:1> exit
octave-gui: ../default/libinterp/corefcn/graphics.cc:2725: void
gh_manager::do_close_all_figures(): Assertion `hlist.numel () == 0' failed.
panic: Aborted -- stopping myself...

The close_test.m script is

y   = randn(100,5);
h   = plot (y);
txt = {'1','2','3','4','5'};
h   = legend (h, txt);
close all


This bug makes all the scripts I am currently using with octave stable crash,
so for me this is quite a severe bug. Let me know if I can be of assistance.
