https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242784 --- Comment #6 from corvid@openmailbox.org --- It gets into print_entry(), and there=E2=80=99s a loop with careless errors in the loop condition: for (p =3D ifnameindex; p && ifnameindex->if_index && ifnameindex->if_name; p++) { if (p->if_index =3D=3D sdl->sdl_index) { xo_emit(" on {:interface/%s}", p->if_name); break; } } sdl->sdl_index is 3, and the list of interfaces has indices 1, 2, 4, 0, some big randomish number, etc. So p just keeps running along until it happens to detect a 3 or segfault. --=20 You are receiving this mail because: You are the assignee for the bug.=
