Valgrind肯定输掉了比赛

Question

Valgrind肯定会丢失8个字节，但我释放了内存。

==11492== 8 bytes in 1 blocks are definitely lost in loss record 3 of 4
==11492==    at 0x4029F6F: malloc (vg_replace_malloc.c:270)
==11492==    by 0x8049778: list_add (list.c:169)

list.c：

169 lnode *n = (lnode *) malloc(sizeof(lnode));
170 n->value = value;
171 syslog(LOG_NOTICE,"in list_add.  added lnode=%p Adding active_allocation n->value=%p\n", n, value);
    ...

245 syslog(LOG_NOTICE,"Freeing (*tmp)=%p\n", (*tmp));

246 syslog(LOG_NOTICE,"(*nptr)->next=%p  &(*nptr)->next=%p\n", (*nptr)->next, &(*nptr)->next);
247 *nptr = (*nptr)->next;
248 *nptr = (*nptr)->next;
249 free(*tmp);             //Free this lnode

list.c日志的第一部分：

Sep 27 00:05:27 appliance m61[11492]: in list_add.  added lnode=0x420abb8 Adding active_allocation n->value=0x42088b0

第二部分记录：
