tty-login fails if another bash is exec'ed in .bashrc: no job control in background
Dear bash-maintainers, Description: When another instance of bash is called *within the .bashrc* using the exec-builtin within a tty (e.g. Ctrl+Alt+F1) the following error occurs: initialize_job_control: no job control in background: Bad file descriptor On the next keypress the user is logged off. This used to work fine in bash 4.4. Repeat-By: Put the following snippet into your .bashrc, but make sure you can change that later on, because the login fails! if [[ -z $foo_exec_test ]]; then export foo_exec_test=123 echo "exec bash" exec bash fi Thanks Best Regards Tycho Configuration Information [Automatically generated, do not change]: Machine: x86_64 OS: linux-gnu Compiler: gcc Compilation CFLAGS: -g -O2 -fdebug-prefix-map=/build/bash-2bxm7h/bash-5.0=. -fstack-protector-strong -Wformat -Werror=format-security -Wall -Wno-parentheses -Wno-format-security uname output: Linux debian-dell 4.19.0-8-amd64 #1 SMP Debian 4.19.98-1 (2020-01-26) x86_64 GNU/Linux Machine Type: x86_64-pc-linux-gnu Bash Version: 5.0 Patch Level: 3 Release Status: release
