+Subject: [PATCH] fix get/unserialize memory corruption
+
+Possible memory corruption (and segfault) after unserialising objects:
+<?php
+$obj = new StdClass;
+$obj->obj = $obj;
+$memcache = new Memcache;
+$memcache->connect('127.0.0.1', 11211);
+$memcache->set('x', $obj, false, 300);
+$x = $memcache->get('x');
+$x = $memcache->get('x');
+$x = $memcache->get('x');
+$x = $memcache->get('x');
+$x = $memcache->get('x');
+
+Patch by Paul Clifford.
