New Comment:
bug has been fixed, will behavior like 5.3
but it's a little weird that's two different drived class will share one same dbh,
and the dbh hold only one drived class instance.
see the test script I committed: https://github.com/php/php-
src/blob/6cd6349ff8842a9356723b7b192eb3c93fb64c7e/ext/pdo_mysql/tests/bug63176.php
t
note the result are all PDO2....
maybe we should also add the drived class name into the persistent id?
thanks

@thz, the workaround I did was to create 2 DNS names for the same DB. So PHP will
think they are 2 different servers and connect twice.

Hi, we are experiencing the same error and it's preventing us from moving to PHP
5.4. Are there any plans to fix this or are we going to have to live with not
being able to derive from PDO?
We have done extensive debugging and may be able to provide some information as
to why this happens, but due to a lack of internal knowledge of how the Zend
engine works, we haven't been able to come up with a fix.

I tested in my PHP 5.3.15 and the issue doesn't happen. It just happen in PHP
5.4.x.

After looking at the patch, is denying persistent connections from derived PDO
classes the actual proposed solution? Not being able to extend \PDO with
persistent connections would be a problem in many frameworks/appliances.
