Description:
------------
PHP crashes when executing a query using PDO/Mysql.
PHP is running as an Apache 2.0 handler.

In the Apache error log, this line appears:
[notice] Parent: child process exited with status 3221225477 -- Restarting.


Sometimes, even the new PDO() call crashes already, but to reproduce the bug easily, just do a SELECT * FROM mysql.user - voila.

Set up: XAMPP 1.7.0 with Apache 2.2.11, PHP 5.2.8, MySQL 5.1.30.
The same crash could be reproduced in a 'bastardized' XAMPP setup with MySQL 5.0.67.
Conversely, the setup Apache 2.2.11, PHP 5.2.6, MySQL 5.1.30 was OK. No crashes here.


Reproduce code:
---------------
$pdo = new PDO("mysql:host=localhost; dbname=mysql", 'root', $mypassword);

$pdo->exec("SET NAMES 'utf8'");

$result = $pdo->query($sql, PDO::FETCH_NUM);

//...bye bye!



Expected result:
----------------
Obvious.

Actual result:
--------------
Apache Error Log:
[notice] Parent: child process exited with status 3221225477 -- Restarting.

Nothing more available.
