[Octave-bug-tracker] [bug #63752] experimental-terminal-widget crashes Octave

[Dmitri A. Sergatskov]

Follow-up Comment #8, bug #63752 (project octave):

Not sure if this is the same thing, but if I run (compiled w/ TSAN) 
TSAN_OPTIONS='ignore_noninstrumented_modules=1' ./run-octave -f --gui
--experimental-terminal-widget

on Wayland it would segfault on exit (but I  could type on therminal w/o
problems). All my computers normally run on Xorg.

If I run (TSAN) 

TSAN_OPTIONS='ignore_noninstrumented_modules=1' ./run-octave -f --gui I get
