Subject: [BUG] builtins with bad file descriptor can hang the shell
Date: Thu, 10 Jun 2021 10:25:50 +0200	[thread overview]
Message-ID: <20210610082550.GB897070@zira.vinc17.org> (raw)

The following first 3 commands are OK. The 4th one hangs zsh,
with Ctrl-C and Ctrl-\ having no effect. This happens whether
MULTIOS is set or not.

zira% echo >&- > >(cat -n)
     1
zira% echo >&2 > >(cat -n)

     1
zira% /bin/echo >&3 > >(cat -n)
zsh: 3: bad file descriptor
zira% echo >&3 > >(cat -n)
zsh: 3: bad file descriptor
