'wg' binary segmentation fault

I am running PFSense 2.5.0-RELEASE. FreeBSD pfsense.host 12.2-STABLE FreeBSD 12.2-STABLE d48fb226319(devel-12) pfSense amd64

I have found a new issue that when I run "wg" or "wg show" via SSH, the binary segfaults when it attempts to display wg2's information.

I'm not certain how to report this further. I ended up running "wg show" on the machine because I had an issue with some hosts not connecting to Wireguard and I ended up rebooting the machine, thinking that the segfault would disappear after a reboot. This is after my reboot.

Last time I saw that happen it was due to an invalid configuration where two peers on the same tunnel had Allowed IPs set to 0.0.0.0/0.

We're adding input validation to prevent that invalid configuration:
