It looks to me like this is a segfault in iptables-restore, not in wg-quick, so i'm reassigning the bug report to the iptables package, which shouldn't segfault, no matter what input it receives. (maybe this is due to sending it empty lines? In the meantime, i believe that more recent versions of wireguard-tools do not send empty lines to iptables-restore. Can you verify that this doesn't happen for you with a more recent version? Thanks for reporting this, --dkg
