Subject 答复:i has a bug to report, it will core dump in zookeeper 3.3.3
Date Mon, 09 Dec 2013 02:53:41 GMT
I have see the source code, in zookeeper.c 2056~2079:
if sc->u.str.str_len is 0, then '\0' will not be set. so when deallocate_CreateResponse(&res)
(this function will free the string sc->u.str.str) it will core.I think it is a bug.
