Bash Version: 4.2
Patch Level: 53
Release Status: release
Description:
Bash 4.3 introduced "-1" for unlimited history.
Starting bash 4.2 with HISTSIZE=-1 in ~/.bashrc causes a segmentation
fault (assuming you have a ~/.bash_history with at least one entry).
This can easily happen if several systems (with different bash
versions) mount the same home directory.
Repeat-By:
$ cat > poc-bashrc <<EOF
HISTSIZE=-1
EOF
# Make sure you have at least one entry in your history file!
$ bash --rcfile ./poc-bashrc
Segmentation fault (core dumped)
# Here's the backtrace.
