Follow-up Comment #4, bug #43054 (project screen): I compiled 4.3.1 & 4.4.0 and tested again on the same system. The same issue still happens.
BTW, it's a 64-bit Debian, in case that matters. Some console output below for your reference: cychoi:~/tmp/screen/screen-4.4.0$ cat screenrc vbell on termcapinfo * vb@ defmonitor on cychoi:~/tmp/screen/screen-4.4.0$ SCREENDIR=. SCREENRC=./screenrc ./screen ... (inside the screen session) cychoi:~/tmp/screen/screen-4.4.0$ echo $STY^G 18361.pts-11.XXXX :windowlist [FREZZE HERE] ... cychoi:~$ ps xf | grep screen 18536 pts/12 S+ 0:00 \_ grep screen 18360 pts/11 S+ 0:00 \_ ./screen 18361 ? Zs 0:00 \_ [screen] <defunct> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?43054> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
