Description:
------------
After making valid SSL connection (using openssl s_client) to server with SSL context PHP segfaults.
I've tested this with latest CLI version bundled with OSX - 5.4.17.

I think issue source can similar to this one: https://mail.python.org/pipermail/python-dev/2013-October/129832.html

Test script:
---------------
<?php
 $serverSSLContext = stream_context_create();
 stream_context_set_option($serverSSLContext, 'ssl', 'local_cert', "./test.pem"); 
 $serverSocket = stream_socket_server("ssl://127.0.0.1:8000", $errno, $errstr, STREAM_SERVER_BIND|STREAM_SERVER_LISTEN, $serverSSLContext);
 while(stream_socket_accept($serverSocket));

Actual result:
--------------
Since gdb isn't supported on Mavericks I've used lldb:
$ lldb php testssl.php
Current executable set to 'php' (x86_64).
(lldb) run
Process 40595 launched: '/usr/bin/php' (x86_64)
Process 40595 stopped
