Can you remove sushosin and get debug symbols for the rest of the php
binary.

I can't reproduce this on 5.2.10-dev or 5.3.0-dev


Output is:
Warning: stream_socket_client(): unable to connect to
ssl://www.google.com:443 (Operation now in progress) in
/private/tmp/test.php on line 7

Error:36: Operation now in progress

Description:
------------
PHPInfo located here:
http://www.wright-family.me.uk/shared/phpinfo.txt

Using hardened profile Gentoo Linux:
Linux beth 2.6.25-hardened-r11 #6 SMP Tue Dec 23 08:37:01 GMT 2008
x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ AuthenticAMD
GNU/Linux

Attached code causes a segfault when executing the
stream_socket_client() function.

Using TCP rather than SSL works correctly (i.e. without a segfault).

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

$context = stream_context_create();
$errno = 0;
$errstr = "";
$socket =
stream_socket_client('ssl://www.google.com:443',$errno,$errstr,60,STREAM_CLIENT_CONNECT,$context);
echo "\nError:{$errno}: {$errstr}\n";

while (($line = @fgets($socket)) !== false) {
        if ($line) {
                $response .= $line;
                if (rtrim($line) === '') break;
  }
}
echo "\n\nHeaders:\n{$response}\n\n";
?>


Expected result:
----------------
Code should connect to google, and attempt to read some data.

Actual result:
--------------
