Hello!

In the last command, cbq_bind_filter is called with parent==0:

Damn, indeed. Congratulations!

It should look like:

+	if (p == NULL)
+	         p = &q->link;
        if (cl) {
-                if (p && p->level <= cl->level)
+                if (p->level <= cl->level)
                        return 0;
                 cl->filters++;
