Description:
------------
I can fix this segfault by either removing the ATTR_PERSISTENT option, or by
assigning parent::prepare to a local variable (i.e. $stmt =
parent::prepare('...'))
Also worth nothing I had to compile PHP as shared due to a bug when trying to
compile the extension with mysqlnd which is filed in a separate report.

Test script:
---------------
<?php
class BuggedPDO extends PDO {
protected $stmt = null;
public function __construct() {
$options = array(
\PDO::ATTR_PERSISTENT => true,
\PDO::ATTR_ERRMODE => \PDO::ERRMODE_EXCEPTION,
);
try {
parent::__construct('mysql:dbname=testdb;host=localhost', 'testuser',
'testpass', $options);
$this->stmt = parent::prepare('select * from table');
} catch (\Exception $ex) {
var_dump($ex);
}
}
}
$test = new BuggedPDO();
Expected result:
----------------
A proper resource in $this->stmt
Actual result:
--------------
