Description:
------------
The following code is crashing the PHP engine (php-cli,php-cgi) when working on Linux OS. Also tried via Microsoft FastCGI wrapper and IIS (IIS-6 and IIS-7).

On Linux OS its working ok.

In order to reproduce, create a new Gmail account, login and enable IMAP service, then, use the code below.

Reproduce code:
---------------
<?php


$connectionString ='{imap.gmail.com/imap/ssl/novalidate-cert/user=USER_NAME@gmail.com}INBOX';
$messageStream = imap_open ($connectionString, 'USER_NAME@gmail.com', 'PASSWORD');


$boxInfo = imap_check($messageStream);

for ($messageNumber = 1; $messageNumber <= $boxInfo->Nmsgs; $messageNumber++)
{
    $headerInfo = imap_header($messageStream, $messageNumber);
    var_export($headerInfo);
}

Expected result:
----------------
You should get the list of your emails.

Actual result:
--------------
Crash of PHP/FastCGI.

This bug is still present in 5.2.14 and 5.3.3 (both VC6 and VC9 builds - TS and NTS).

It looks like any of the calls in this extension when used with SSL (IMAP, POP, or NNTP) result in a crash on Windows - "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."

Can someone please help?

IIRC, this code works just fine here. Which version do you exactly? From where did you get it, which SAPI, etc.
