In fact bug #55029 was due to a change in glibc. So unless you are using a version of Octave that was built using gcc, this is probably not exactly the same bug. I'll CC Andrew Janke who may have a dev version for testing.

I'm not very sure whether this is a duplicate of bug #55029

In GNU/Linux, this bug has been fixed on the upcoming version 5.2.0, but I don't know about Mac OS.

Octave's pause function doesn't respond to key presses when executed without arguments.

Rather, it simply pauses the program indefinitely, with no way to resume program execution. I discovered this while working through Andrew Ng's ML course using Octave, where I had to simply comment out the pause commands in order to run the scripts.

Other test cases:

1. "r = [1;2;3]; pause; f=[3;4;5]" in the repl will freeze indefinitely

2. "r = [1;2;3]; pause(0.05); f=[3;4;5]" will freeze until key press if the time determined by the argument has passed. Else, it will not respond to key press.

3. using "pause (0.05)" in Ng's ML scripts will work as expected.

By key press, I hold the same definition defined in the documentation.
