Description:
------------
When I add the same server to pool and use persistance connection it will generate segmentation fault for getExtendedStats

Reproduce code:
---------------
    $memcache_obj = new Memcache;
    $memcache_obj->addServer('localhost', 11211);
    $memcache_obj->addServer('localhost', 11211);
    //$memcache_obj->addServer('failed_host', 11211);
    
    $stats = $memcache_obj->getExtendedStats();
    print_r($stats);

Expected result:
----------------
No segmentation fault

Actual result:
--------------
segmentation fault

We had the same thing happening without persistent connections 
when upgrading to memcache 3.0.x.  PHP version 5.3.6, 
memcached 1.4.5 and memcache version 3.0.6.  Rolling memcache 
back to 2.2.6 fixed it.

The official bug tracker for PECL/memcache is now at
<https://github.com/websupport-sk/pecl-memcache/issues>.

So, if this is still an issue with either of the current memcache
versions (4 or 8), please file an issue there.
