Summary: Segmentation fault when instantiate 2 persistent PDO
to the same db server
Status: Assigned
Type: Bug
Package: PDO related
Operating System: Ubunt 12.04.1
PHP Version: 5.4.7

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)
------------------------------------------------------------------------
