Details:

Launch octave --gui, type


containers.Map()


Press Enter, close the GUI. Output:


[user@machine ~]$  octave --gui
[1] 294
[user@machine ~]$  fatal: caught signal Segmentation fault -- stopping
myself...
octave exited with signal 11
[user@machine ~]$


Also happens with bare containers.Map, i.e. without parentheses.

The CLI interface does *not* raise the error message.

Happens on 5.1.0 from Fedora 31.
Does not happen on 4.4.1 from Debian 10.
