[Bug 1562658] [NEW] screen caught signal 11 core dumped

[Fake Name]

Public bug reported:

This is a duplicate of
https://bugs.launchpad.net/ubuntu/+source/screen/+bug/1333630

However, 1333630 is incorrectly marked as fix released, and after a year
of occationally attempting to get someone to notice that 1333630 is not
fixed, I'm giving up and opening a new bug in hope of someone actually
noticing.

Basically, the version of screen in the 14.04 "long term support"
release can occasionally segfault, taking all contained shell sessions
down with it. This is extremely annoying if you use screen extensively,
and having to compile screen from source on every ubuntu install I use
is ridiculous.

The underlying issue was a bug in  GNU screen:
https://savannah.gnu.org/bugs/index.php?35757

This was fixed fully one year ago. However, the version of screen that's
distributed as part of ubuntu is apparently **10** years old (Screen
version 4.01.00devel (GNU) 2-May-06).

Since 14.04 is ostensibly still supported, can someone please actually
support it, and upgrade the version of screen to something from the last
year?

There is screen 4.2.1 in trusty/backports, but 1) this bug was not fixed
until 4.3.0, and 2) this is a core shell util, I shouldn't have to go
hunting for a additional repository to get a functional version of the
GNU tools that's usually installed by default.
