BTW,

(kgdb) list *0xc015daff
0xc015daff is in malloc (/mnt/se3/releng_4/src/sys/kern/kern_malloc.c:244).
239                     freep->next = savedlist;
240                     if (kbp->kb_last == NULL)
241                             kbp->kb_last = (caddr_t)freep;
242             }
243             va = kbp->kb_next;
244             kbp->kb_next = ((struct freelist *)va)->next;
245     #ifdef INVARIANTS
246             freep = (struct freelist *)va;
247             savedtype = (const char *) freep->type->ks_shortdesc;
