Version 1.7.0: php_pdo_mysql crashing

[olagato]

I've just installed lastest version 1.7.0 and all my web projects with PDO MySQL access are crashing
(working fine in 1.6.8 version)
I've tried to execute the procedure recommended by Wiedmann in this post http://community.apachefriends.org/f/viewtopic.php?f=16&t=32540, but the problem still persists:

Go to the directory "\xampp\mysql\bin" and execute the programm "mysql_update.exe".

Error details from Microsoft:
- szAppName : apache.exe
- szAppVer : 2.2.11.0
- szModName : php_pdo_mysql.dll
- szModVer : 5.2.8.8
