Description:
------------
setrawcookie seems to be the cause of this bug but it actually requires a couple things to trigger. The rawurlencode and the PDO statement seem required.

I'm not sure how to get gdb working right with php-fpm where I triggered this bug. Because of the cookie involved it obviously doesn't work from the command line though.

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

setrawcookie('cookie', rawurlencode('value'), $_SERVER['REQUEST_TIME'] + 31536000, '/');
$dbh = new PDO('mysql:host=localhost;dbname=data', 'root', '');


Expected result:
----------------
cookie is set

Actual result:
--------------
502 response and SIGSEGV in log
