Details:
This issue has been submitted originally in Debian by Thorsten Glaser
<address@hidden> under https://bugs.debian.org/831672 -- citing from there:
-----------------------------------------------------------------
cat >.screenrc
bind u digraph U+
^D
screen
^Au
… leads to…
[screen caught signal 11. (core dumped)]
Getting a backtrace is unfortunately not as easy, but
with sudo gdb screen I can at least get it interactively.
(gdb) bt
#0 0x00007fe709acde10 in __pause_nocancel () at
../sysdeps/unix/syscall-template.S:84
#1 0x0000556d56004524 in Attacher () at ../attacher.c:628
#2 0x0000556d55fdf2d0 in main (ac=0, av=<optimized out>) at ../screen.c:1275
-----------------------------------------------------------------
The crash seems to be architecture dependent and I can reproduce it on x86_64
(aka amd64) with:
* 4.4.0 as packaged by Debian
* built from git's HEAD of the screen-v4 branch
* 4.3.1 built from git's v.4.3.1 tag
