Description:
------------
Attempting to write a large buffer to a non-blocking encrypted stream will fail, as SSL_write() expects to be passed the *exact* same buffer (same ptr addr) for successive calls.

Test script:
---------------
<?php

$fp = stream_socket_client("tcp://lxr.room11.org:443");
stream_set_blocking($fp, false);
while (!stream_socket_enable_crypto($fp, true, STREAM_CRYPTO_METHOD_ANY_CLIENT));
var_dump(fwrite($fp, "POST / HTTP/1.1\r\nHost: lxr.room11.org\r\nContent-Type: text/plain\r\nContent-Length: 131072\r\n\r\n"));
$data = str_repeat("a", 65536);
var_dump(fwrite($fp, $data));
var_dump(fwrite($fp, $data));
var_dump(fwrite($fp, $data));

Expected result:
----------------
No errors

Actual result:
--------------
error:1409F07F:SSL routines:ssl3_write_pending:bad write retry
