For Windows (installer):

I've tried to replicate the problem, but for me valgrind reports no 
errors.

Description:
------------
There were some crashes with 5.2.4 when using pdo, so i've tried out
5.2.5 that seems to have fixed this crashes.
Just to make sure there was no problem, i've tried to valgrind the
command line program on a simple script using pdo.
There are a few memory errors (this can make crashes occur).
Note that the leaks are due to the kernel 2.4 threads (so, ignore
them).


Reproduce code:
---------------
<?php

$dbh = new PDO('mysql:host=host;dbname=db', 'user', 'pass',
array(PDO::ATTR_PERSISTENT => true));

?>


Expected result:
----------------
No memory errors

Actual result:
--------------
Valgrind's output

> valgrind -q --leak-check=full --show-reachable=yes
