I think this is indeed a duplicate of bug #42469. The info in comment #6 leads me to believe that bug #42469 is fixed with Qt 5.

The solution seems to be to use Qt 5 (which will be the case eventually for all users) or to disable autocompletion in the editor.

Torsten, on my OpenSuse Tumbleweed-pc I have libqscintilla2_qt5-13 (2.10-2.3) and libqscintilla_qt5-devel (2.10-2.3) installed. On my Linux Mint-pc I have libqscintilla2-12v5 (2.9.2+dfsg-3build1) and libqscintilla2-l10n (2.9.2+dfsg-3build1) installed. On both pc's I have fcitx input method installed, but when I work with Octave it is just my keyboard (Germany) activated.

No, when I type '-sign or even if I activate my kyrilic input method - crash does not happens.

Andriano, do you have different versions of QScintilla installed on the two systems or are you using different keyboards?

In addition, does the crash happens when typing ' or other dead letters as described in bug #42469 or also for other inputs?

Yes, without autocompletion Editor works fine. But on my second pc (OpenSuse Tumbleweed) Editor works fine also with autocompletion. bug # 42469 says that there is an error in Qscintilla (if you use ibus input method). On both computers I use fcitx input method (disabled when working in Octave).

Does the editor work as expected when you disable the autocompletion? If so, this bug seems to be a duplicate of bug #42469.

I have the same problem. I type in Editor-Window just:

   data = abc
   data =

and octave crashes with message in terminal: 'octave exited with signal 11'. It happens even if I edit some other m-files. I have Linux Mint 18.2 KDE Edition. Octave installed from: ppa:octave/stable. I think it has something to do with the autocomplete function.

Thank you for the report. I can't reproduce this issue on ubuntu 16.04 LTS with current stable or default branch.

Is the "\" at the end of the input required for the crash? Does this also happen when you try to save the new tab that is automatically opened when the editor comes up with no other file opened?

Distributive: ubuntu 16.04.3
GNU Octave from ppa:octave/stable
Steps for obtaining:
1) File->New->New Script
2) Input some text, for example print('Insert some variable')\
Octave crashes with "octave exited with signal 11" message in console window. If it's not crashes, try to save file and it will crash.
