Subject: 24.5; Running 'bash -i -c' via shell-command hangs on FreeBSD
Date: Sat, 21 Nov 2015 06:20:26 -0800

On FreeBSD, running:

  M-x shell-command
  /usr/local/bin/bash -i -c "echo hello"

hangs until you press C-g (twice). I can see the bash process running at
100% via `top` until C-g kills it.

Adding `--norc --noprofile` to the command still hangs, so it's not
anything about the shell initialization files. The `-i` option is the
key: without it, everything works fine.

Running the same command via `async-shell-command` does not hang: Bash
outputs "hello" in the "*Async Shell Command*" buffer and exits.

Both Emacs and Bash are standard FreeBSD 10 binary packages installed
via `pkg`. (emacs24-24.5_1,3 and bash-4.3.42, respectively).

Thanks for reporting back.  With the above, I'm closing this bug report.
