 Ticket: new
 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.
