Thanks for testing. This looks like a duplicate of bug #42469.

Does not crash with autocomplete disabled! To be more specific, it's the auto-complete list that causes the crash (Edit > Preferences > Editor > Auto-complete > Automatically exhibit auto-complete list).

I use 4.0.3 because it is the one on Fedora repo (octave-6:4.0.3-1.fc25).

Thanks for the response.

Does the crash also occur when you disable the autocompletion?

Works for me with 4.2.1.
(4.0.3 is old and unmaintained).

On Octave's editor, writing "â" makes Octave crash to desktop (no error message given).

How to reproduce:
1. Open Octave;
2. Go to the editor tab;
3. Write the following:
As soon as you write the "â" character, Octave will crash.

NOTE: writing just an "â" (as the first character) or several of them doesn't result in a crash. Other characters instead of "dist" also result in a crash, when followed by "â" or other Latin-accents (e.g. "ã"). Seems to only crash after an specific number of characters before the accentuated one.

Writing the accent character before the rest of the word DOES NOT result in a crash, e.g.:
1. Write "â" in the editor;
2. Move the cursor before the letter;
3. Write "dist";
4. Move the cursor to the end of the line;
5. Write anything.
No crashes will occur, HOWEVER, if you write any accent after that, it will crash.
