Hi,

I can reproduce this issue systematically when most of the terminfo are
missing:

# systemd-nspawn -D /var/tmp/systemd-test.219Nte/nspawn-root/
Spawning container nspawn-root on /var/tmp/systemd-test.219Nte/nspawn-root.
Press ^] three times within 1s to kill container.
-bash-5.0# find /usr/share/terminfo/
/usr/share/terminfo/
/usr/share/terminfo/l
/usr/share/terminfo/l/linux
-bash-5.0# echo $TERM
linux
-bash-5.0# export TERM=dumb
-bash-5.0# export TERM=linux
munmap_chunk(): invalid pointer
Container nspawn-root terminated by signal SEGV.
