Subject: zsh 5.1 freezes with zombie child
Date: Wed, 2 Sep 2015 01:07:43 +0200 [thread overview]
Message-ID: <20150901230743.GA12128@zira.vinc17.org> (raw)
I did with zsh 5.1:
1. Run "emacs some_file &"
2. Run "less some_other_file"
3. Quit emacs.
4. Quit less.
The result is a frozen zsh with a zombie child corresponding to less.
100% reproducible.
The backtrace:
