If you want to use Octave in terminal mode, you might consider using "octave-cli" instead of "octave --no-gui", they are slightly different. Does using octave-cli resolve this bug for you?
If not, and if you are able to upgrade to a newer version of Ubuntu, are you able to reproduce this in Octave 4.2.1, which is available in Ubuntu 17.10 or 18.04? ** Changed in: octave (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1695281 Title: GNU octave crashes reliably after a simple input sequence To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1695281/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
