[Octave-bug-tracker] [bug #51903] Ctrl-Z causes multiple "^Z" echos at octave prompt

[Guillaume]

Follow-up Comment #5, bug #51903 (project octave):

I can actually reproduce this as well. Pressing Ctrl-Z once and there is a
stream of ^Z appearing. If I then press Ctrl-C to stop, I get a segmentation
fault:


octave:1> a=1
a =  1
octave:2>
