screen(1) crashes plus weird output for screen -ls

[Kover Attila]

Hi,

I have some old RPi images which I was build (I use a modified image build script from kernelnomicon.org), the oldest is r252056 from June 2013. I was a distant memory that screen was worked some months ago, so I was booted that old image, compiled screen from ports (r350213, recently fetched with svn) and the test shows that it is work with the old kernel version.

root at freepi:~ # screen -ls
There are screens on:
        561.pts-0.freepi        (Attached)
        568.pts-2.freepi        (Detached)
2 Sockets in /tmp/screens/S-root.

root at freepi:~ # uname -a
FreeBSD freepi 10.0-CURRENT FreeBSD 10.0-CURRENT #0 r252056M: Fri Jun 21 17:59:17 CEST 2013     root at dlc-10c:/root/ujra/svnhead/obj/arm.armv6/root/ujra/svnhead/head/sys/RPI-B-DRS  arm
root at freepi:~ # screen --version
Screen version 4.00.03 (FAU) 23-Oct-06
