Description:
------------
When using stream_get_contents() without the $maxlength argument, the warning "Warning: Invalid CRT parameters detected" is showing up. This only happens in PHP 5.3.1, it works correctly in PHP 5.2.12.

Adding a very large value to $maxlength, even much larger than the actual content to be retrieve makes the warning go away.

Reproduce code:
---------------
<?php
$sock = fsockopen("127.0.0.1",80);
$writeStr = "GET / HTTP/1.0\r\n\r\n";
for ($written = 0; $written < strlen($writeStr); $written += $fwrite) {
   $fwrite = fwrite($sock,substr($writeStr,$written));
   if (!$fwrite) break;
 }
$data = stream_get_contents($sock);
var_dump($data);
?>

Expected result:
----------------
The warning "Warning: Invalid CRT parameters detected" should not show up, it does not in PHP 5.2.12. In both PHP 5.2.12 and 5.3.1, $data is containing the same thing.

Actual result:
--------------
Warning: Invalid CRT parameters detected in D:\wwwroot\Dev\Framework_TestApp\bug.php on line 8
string(726) "HTTP/1.1 200 OK

I cannot reproduce this bug in PHP 5.3.2+. This version seems to have solved it but I cannot find any related solved bug in the release notes.
