OK, so it looks to me like the problem comes when feeding this set of
commands into iptables-restore.
But hm, i'm still having trouble replicating the segfault.
Is this still happening for you?
Can you send the output of these two commands?
dpkg -l iptables wireguard
dpkg -S $(readlink -f $(which iptables-restore))
That might help us narrow down the cause of the segfault.
Sorry for how long this is taking to debug!
