$ screen -ls irc
There is a screen on:
        5132.irc        (01/12/2015 04:03:49 PM)        (Detached)
1 Socket in /var/run/screen/S-dtucker.

$ echo $?

This is not ideal for scripts that check for an existing screen session. The
error appears to be on line 1182 of src/screen.c where a Panic call is made,
but I'm not sure how to fix it. Somehow I don't think printf + exit calls will
do it here.
