Octave crashes when opening an m file

Asked by Spyros Theodoritsis

When double clicking on an m file Octave opens and crashes immediately. When opening Octave first and then open the m file from menu then no crash occurs.

Bug description seems better suited to an explanation of why Octave is behaving the way it is.

When an m file is opened with Octave by double-clicking on it, the file is executed as a script. Octave's current behavior when given a script on the command line is to run the script to completion and then exit, similar to how other command interpreters work. The effect of this is that the Octave GUI will appear for the duration of the m file and then exit when it is finished executing. If the m file finishes quickly, it may appear that Octave is starting and crashing immediately, but it is in fact operating correctly.

To execute a script and keep Octave's command window up ready to use interactively, add the --persist option to the command line.

Can you help with this problem?
