This is on the current release of OpenWrt so previous release of nft. Same behavior on x86, aarch64 and mips. All other commands from my monkey testing just return silently, only this one fails. $ uname -a Linux rtr00 5.15.137 #0 SMP Tue Nov 14 13:38:11 2023 x86_64 GNU/Linux $ nft -V nftables v1.0.8 (Old Doc Yak #2) cli: no json: yes minigmp: yes libxtables: no $ nft list ct expectation table inet fw4 Segmentation fault
