3 years ago Thank you for filing the bug report!
If I understood the situation correctly, you started another interpreter from bash, then pressed TAB while in the prompt for that interpreter, Emacs froze and eventually you got an error message. This is wrong: bash-completion.el should detect quickly that it's not talking to bash anymore and fall back to a default completion.
I'll find a way of fixing that.
In the meantime, to avoid this issue if it annoys you, I'd suggest adding the following to your .emacs as a workaround:
(setq bash-completion-use-separate-processes t)This tells bash-completion.el to always start a separate bash process to communicate with, so the situation just doesn't arise. The drawback is that, since completion happens on a different bash process, any function you added or any variable you set in your shell process will not be completed.

Hello, This is what bash-completion-debug shows:
This buffer contains information about the last completion command and the BASH process it was sent to. This can help you figure out what's happening.
If it doesn't, go to https://github.com/szermatt/emacs-bash-completion/issues/new to create a new issue that describes:
Then add a copy of the information below:
