+Subject: [PATCH 57/81] nscd: Drop local address tuple variable [BZ #29607]
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When a request needs to be resent (e.g. due to insufficient buffer
+space), the references to subsequent tuples in the local variable are
+stale and should not be used.  This used to work by accident before, but
+since 1d495912a it no longer does.  Instead of trying to reset it, just
+let gethostbyname4_r write into TUMPBUF6 for us, thus maintaining a
+consistent state at all times.  This is now consistent with what is done
+in gaih_inet for getaddrinfo.
+
+Resolves: BZ #29607
