Hello,

it seems like the following commit introduced a bug.

commit cdd2a8c360c70d16804ace7cc923a6c6bb7c9ca9
Author: Sami Kerola <kerolasa@iki.fi>
Date:   Wed Apr 4 19:44:04 2012 +0200

    term-utils: verify writing to streams was successful

    Signed-off-by: Sami Kerola <kerolasa@iki.fi>

Before the commit

script -e -c "echo"
echo $?
0

After the commit

script -e -c "echo"
echo $?
1

I think what happens is that we first close stderr in dooutput (as
timingfd) and then we try to close it again in atexit(close_stdout),
causing the error.

In fact redirecting timingfd to a file fixes it

script -t/tmp/a -e -c "echo"
echo $?
0
