 New Comment:

After looking at the patch, is denying persistent connections from derived PDO 
classes the actual proposed solution?  Not being able to extend \PDO with 
persistent connections would be a problem in many frameworks/appliances.

Description:
------------
Download the PHP version 5.4.7, compiled with ./configure --enable-debug --with-
pdo-mysql --enable-pcntl

Run the test script and it gives a segmentation fault when the script finish. 
If 
I remove the attribute from PDO2 it works fine. If the persistent option is 
disabled it works fine too.

gdb backtrace available on https://gist.github.com/3bda9d5253e7a86168e0


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

class PDO2 extends PDO {
        protected $transLevel;
}

class ModelA {
        public function __construct() {
                $this->db = new PDO2('mysql:host=localhost', 'root', 'root', 
array(PDO::ATTR_PERSISTENT => true));
                $this->db->query('SELECT 1')->fetchAll();
        }
}

$a = new ModelA();
$b = new ModelA();


Expected result:
----------------
No segmentation fault

Actual result:
--------------
Segmentation fault (core dumped)


------------------------------------------------------------------------
