Description:
------------
Having massive problems with beta3. __construct calls __construct in eg. mysql-Driver which is leading to an endless loop of constructors

Bug occurs in PHP 5.0.3, upgraded to 5.10-dev and there it works?!

Reproduce code:
---------------
$dsn = array(
"phptype" => 'mysql'
"username" => 'test'
"password" => 'test'
"hostspec" => 'localhost'
"database" => 'test'
);

$db =& MDB2::connect($dsn);

Expected result:
----------------
A connect to a database

I dont see how there could be an infinate loop from looking at the code (was looking at CVS, but I dont remember making any changes to the CVS in the constructors). Could you also give PHP 5.0.4 a try?

Sorry, seems the bug is not in MDB2beta3 but in eaccelerator 0.92a. After disabling eaccelerator MDB2beta3 works fine, but with eaccelerator enabled I get this (via xDebug):

Fatal error: Maximum function nesting level of '100' reached, aborting! in /usr/local/lib/php/MDB2/Driver/mysql.php on line 1073

16 MDB2_Driver_mysql->__construct() /usr/local/lib/php/MDB2.php:1073

and so on.

I should wait for stable releases ;-)

Thanks for developing MDB2 and keep on the great work!

reporter notes its a bug in "eaccelerator" not MDB2
