Description:
------------
I've used expect to connect through telnet to servers. When first some servers are accessible and next is inaccessible (timeout while connect), I've got memory fault.
When I first try to connect to inaccessible server, at the end I've got another error: /usr/Ports/work/usr/ports/lang/php5/work/php-5.3.5/main/streams/streams.c(400) : Stream of type 'STDIO' 0x2882762c (path:logs/192.168.188.40_2011_01_20_11_10_52.log) was not closed.
In code below $rows is an array of servers.

Reproduce code:
---------------
ini_set('expect.timeout', '3');
ini_set('expect.loguser', 'Off');
ini_set('expect.match_max', 10000);
	
$prompt = array(
'shell' => array('.*[>#].*', 'shell', 3),
'login' => array('>>User (name|password):', 'login', 3)
);
$expect_prompt = array_values($prompt);

foreach ($rows as $eqbase) {
	echo "start connect to {$eqbase['eqbase_ip']} ({$eqbase['eqbase_id']})\n";
			
	ini_set('expect.logfile', 'logs/'.$eqbase['eqbase_ip'].'_'.date('Y_m_d_H_i_s').'.log');
	$stream = expect_popen('telnet '.$eqbase['eqbase_ip']);
	echo "opened\n";
	$res = expect_expectl($stream, $expect_prompt, $matches);
	$reason = '';
	switch ($res) {
		case EXP_EOF:
			$reason = "EOF reached\n";
			break;
		case EXP_TIMEOUT:
			$reason = "Timeout\n";
			break;
		case EXP_FULLBUFFER:
			$reason = "No prompt pattern matched\n";
			break;
	}
	echo $reason;
	if ($res < 0) {
		echo "closed\n";
		fclose($stream);
		continue;
	}
	fwrite($stream, "login\n");
	$res = expect_expectl($stream, $expect_prompt, $matches);
			
	fwrite($stream, "pass\n");
	$res = expect_expectl($stream, $expect_prompt, $matches);

	fwrite($stream, "quit\ny\n");
	$res = expect_expectl($stream, $expect_prompt, $matches);
	echo "closed\n";
	fclose($stream);
}

Actual result:
--------------
When first servers is accessible, I've got:

start connect to 192.168.188.5 (1019)
