The "_complete" command gets into the debugger

[gmdmi]

This happens when shell autocomplete is used.

How do you configure shell autocompletion? Do you have a reliable way to reproduce it?

I use Ubuntu 22.04.

sudo apt install bash-completion
./yii completion bash | sudo tee /etc/bash_completion.d/yii

Restart your shell.
