Works fine for me with 4.4.0-4 on Debian Unstable, too.

What is strange and confusing in that bug report is that the original
reporter says he got the error message "terminal name too long. (max.
20 char)". But at least Screen 4.4.0 has MAXTERMLEN set to 32 in os.h.
(So unless Fedora patches that value as we do in Debian for backwards
compatibility, it's not Screen 4.4.0 issuing that error message.)

So for me it's likely that the issue is in an older version of screen.
The original reporter also wrote something about a pending upgrade. So
I assume that the version number in the report is moot.

About the crash, my only idea is that this might be related to using
new client with old server process or similar as they might use
different values for some of these constants. But I'm not sure at all
if that can cause such a crash as I mostly experienced hanging (but
still living) clients or some features (e.g. window resizing) not
working when client and server have different versions.

                Kind regards, Axel
