[Octave-bug-tracker] [bug #65312] "__run_test_suite__" ran in GUI hangs Octave in some configurations

[Markus Mützel]

Follow-up Comment #4, bug#65312 (group octave):

Nice catch!

I also thought sometimes that the GUI and the interpreter are "fighting" over
the current working directory if it changes often.

Does the following change avoid the issue for you? Also with checked
"Synchronize Octave working directory..."?

This just treads the symptom. I don't know where the actual issue would need
to be fixed. (Maybe, it's a race condition for changing the directory from the
interpreter thread and the GUI thread?)
