Description:
------------
I don't use MySQL anymore, so I have deactivated all MySQL extensions in the php.ini. 

After the update to PHP 5.6beta1 (from 5.6alpha3), I couldn't load the phpinfo() anymore and get the following error, right after the beginning of a "mysqlnd" part (which shouldn't be there):

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 133955572 bytes) in C:\Apache24\htdocs\info.php on line 2

Test script:
---------------
<?php
phpinfo();

Expected result:
----------------
phpinfo() output without MySQL and without memory error

Actual result:
--------------
phpinfo() including a MySQL part with the following output (after that, the output ends):

mysqlnd
