Bash crashes on detaching Screen

I use GNU Screen along with Bash for my SSH sessions.

While detaching my Screen sessions I came across a weird Bash bug and I'd like your help in debugging this issue.

When I attempt to detach a running Screen session using `screen -Drr ,session name` command, the original shell which contained the screen session does not return to a prompt. It instead remains hung and a while later I get the message:

Warning: Program '/bin/bash' crashed

I'm running Arch Linux with Bash 4.3.30(1) and Konsole. I attempted to detach and reattach a screen session from Terminator and did not experience any crashes in Bash.

However, when I attempted the same from a virtual Terminal instead of an emulator, upon remotely detaching the screen session, my terminal directly displayed a login prompt again. This leads me to believe that Bash did crash even then and caused the login prompt to reappear.

Thanking You,
Darshit Shah
