Subject: Initialize buffer before calling res_ninit
Component: krb5-libs
Version_Reported: 1.5.1
Target_Version: 1.5.2
Tags: pullup

Per Paul Vixie: It is necessary to zero out the statbuf before calling
res_ninit(), or else res_vinit() will call res_nclose() and res_ndestroy()
with stack trash as a statbuf, and they will call free() with stack trash,
and programs will dump core.
