Bug description: imap_open causes a segmentation fault
Description:
------------
I was trying to get a simple script to work which simply opened a
connection to the mail server and then closed it but when I ran the script
it caused a segmentation fault on the imap_open line.
Reproduce code:
---------------
<?php
$mailbox = '{mail.hddbroker.com:143}INBOX';
$username = 'xxx';
$password = 'yyy';
$mbox = imap_open($mailbox, $username, $password);
imap_close($mbox);
?>
If I run the script via the CLI version of PHP it prints "Segmentation
fault (core dumped)". If I run the script via a web server, an empty page
is returned.
Expected result:
----------------
In this particular script I expected the imap_open function to return a
resource object.
Actual result:
--------------
I configured my PHP with --enable-debug and followed the steps to get the
following backtrace:
