Problem with PDO+error_handler

Hi! I'm having a problem with PDO. I update my server (php+pdo). And now error in my querys in PDO are not calling the function that I set with set_error_handler(). So, I try setting attribute PDO::ATTR_ERRMODE to PDO::ERRMODE_WARNING. I start calling my function but it's not completing the node "query" in the vars array. So I cant log what query are giving me errors. Anyone had this issue? should I post it as a Bug?
