upstream report: https://savannah.gnu.org/bugs/index.php?66147 1: start a single instance of screen
2: Inside screen, try to use the -X flag to run screen commands from the shell, e.g. "screen -X register . clean-cut-paste"
screen terminates when trying to run commands from the command line. From inside screen, when running a single instance of screen, running "screen -X register . clean-cut-paste" causes a core dump. The same happens for other commands, e.g.:
> screen -X echo a
*** buffer overflow detected ***: terminated
zsh: IOT instruction (core dumped) screen -X echo a
Also, the problem occurs the same whether running "screen -X" from inside or outside a screen session, I just reported what made me aware of the problem first.
