Description:
------------
If I use stream_copy_to_stream with source stream being not file (say, HTTP socket) then I get this warning:

Warning: Invalid CRT parameters detected

This is because in _php_stream_copy_to_stream_ex() php_stream_stat() is applied to source stream, which goes to php_sockop_stat which calls fstat, which produces "invalid parameter" pseudo-exception. 

Reproduce code:
---------------
$socket = open_http_socket();
$fp = fopen("data", "w");
stream_copy_to_stream($socket, $fp);

Actual result:
--------------
Warning: Invalid CRT parameters detected

Is it really that hard to find a script that opens http socket in the manual? OK, here it goes:

<?php
$socket = fsockopen("localhost", 80, $errno, $errstr, 30);
if (!$socket) {
    echo "$errstr ($errno)<br />\n";
} else {
    $out = "GET / HTTP/1.1\r\n";
    $out .= "Host: localhost\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($socket, $out);
}
$fp = fopen("data", "w");
stream_copy_to_stream($socket, $fp);
