Subject: Unexpected behavior with pipe_fail and err_return
To: Zsh Users <zsh-users@zsh.org>
Content-Type: text/plain; charset="UTF-8"

() {
  emulate -L zsh -o pipe_fail -o err_return
  false | while false; do; done
  echo $?
}

This prints "1". Is this expected? I was hoping for no output.

Roman.
