Open a new terminal and then key in:

% x=10
% $((x/10))
zsh: command not found: 1

Then press up key and the cursor will blink between the first and last lines of the terminal. Then press ctrl+c and key in something and then the window of terminal will disappear. And the htop will display that zsh occupies a significant amount of CPU time.

Huh, I weird. I'm indeed able to reproduce this. Strangely enough, though, it doesn't always happen for me. Will have to investigate. Help welcome! 🙂

[marlonrichert]

@PoonKinWang I still haven't found a reliable way to reproduce this. Your example sometimes triggers the bug for me, but not always. It definitely never triggers for me in the test that you included.

Could you try to find a test case that always reliably reproduces the problem?

FWIW, I also get this issue quite frequently when browsing the history. Haven't found a way to reproduce it though.

I can reproduce it every time I activate a conda environment and browse the history
