https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207080 --- Comment #4 from Kristof Provost <kp@freebsd.org> --- Yeah, so this: =3D=3D17184=3D=3D by 0x404B46: pfctl_rules (pfctl.c:1486) =3D=3D17184=3D=3D by 0x406DA7: main (pfctl.c:2378) =3D=3D17184=3D=3D Address 0x6aa8a08 is 56 bytes inside a block of size 64 = free'd =3D=3D17184=3D=3D at 0x4C1E2DC: free (in /usr/local/lib/valgrind/vgpreload_memcheck-amd64-freebsd.so) =3D=3D17184=3D=3D by 0x4210A0: superblock_free (pfctl_optimize.c:1640) =3D=3D17184=3D=3D by 0x4233BE: pfctl_optimize_ruleset (pfctl_optimize.c:= 357) =3D=3D17184=3D=3D by 0x40453B: pfctl_load_ruleset (pfctl.c:1297) =3D=3D17184=3D=3D by 0x404B46: pfctl_rules (pfctl.c:1486) =3D=3D17184=3D=3D by 0x406DA7: main (pfctl.c:2378) Is likely the reason your pfctl segfaults. There's a use after free. It's n= ot the direct cause though, that's the kernel rejecting your rules. Would it be possible to upgrade the machine to stable/10? It looks like the problem is fixed there. --=20 You are receiving this mail because: You are on the CC list for the bug.=
