php-pecl-memcache code is crashing on ppc64 (segfault) - not on i386, x86_64, not sure about s390x yet.
Always reproducible, memcached service must be running. package version:
php-pecl-memcache-3.0.5-1.el6.ppc64
memcached-1.4.4-3.el6.ppc64
php-cli-5.3.3-3.el6

How to reproduce
-----
1. install and start memcached service - leave default settings as it is
2. php ./delete.php 

<?php
$c = new Memcache();
$c->connect("127.0.0.1", 11211);
var_Dump($c->set("rhts638887", "testing delete"));
var_Dump($c->delete("rhts638887"));
