Description:
------------
I have a memcache (version 1.4) setup working on my PHP 5.0.4 config. 

When I try to subclass the memcache class I get some unexpected results when I call the connect() function. It connects allright, but changes the type of the class, and "forgets" the variables the class allready had. 

I allready took a peek in the memcache.c sourcefile, and I think the problem is on line 1418 or 1419, but I have no idea how to fix the problem. Is there anybody who van help me?

PHP configure line: './configure' '--prefix=/usr/local/lib/php5' '--with-mysql=/usr/local/mysql/' '--with-apxs2=/usr/local/apache2-php5/bin/apxs' '--with-gd=/usr/local/'

Lines added in php.ini: 
extension=memcache.so

Reproduce code:
---------------
<?
$memcache = new MemcacheConnection( "localhost" );
var_dump($memcache);
$memcache->connect();
var_dump($memcache);

class MemcacheConnection extends Memcache 
{
	private $host, $port, $persistent;
	
	function __construct( $host, $port = 11211, $persistent = false ) {
		$this->host = $host;
		$this->port = $port;
		$this->persistent = $persistent;
	}

	function connect() {
		if( !parent::connect( $this->host, $this->port ) )
			throw new Exception( "Could not connect to memcache on ".$this->host );
	}
}
?>

Expected result:
----------------
object(MemcacheConnection)#1 (3) {
  ["host:private"]=>
  string(9) "localhost"
  ["port:private"]=>
  int(11211)
  ["persistent:private"]=>
  bool(false)
}
object(MemcacheConnection)#1 (3) {
  ["host:private"]=>
  string(9) "localhost"
  ["port:private"]=>
  int(11211)
  ["persistent:private"]=>
  bool(false)
  ["connection"]=>
  resource(4) of type (memcache connection)
}


Actual result:
--------------
object(MemcacheConnection)#1 (3) {
  ["host:private"]=>
  string(9) "localhost"
  ["port:private"]=>
  int(11211)
  ["persistent:private"]=>
  bool(false)
}
object(Memcache)#1 (1) {
  ["connection"]=>
  resource(4) of type (memcache connection)
}
