Description:
------------
same problem as described here for mysqli ( http://bugs.php.net/bug.php?id=42548 ) seems to exist in the mysql extension. I get the same error message when trying to call a PROCEDURE in MySQL.

The Error-Message:

1312 - PROCEDURE databsename.select_user_login can't return a result set in the given context )

Reproduce code:
---------------
procedure has been added by sql-query:

DELIMITER |

CREATE PROCEDURE `select_user_login` 
(
  IN  `v_email`     varchar(128),
  IN  `v_password`  varchar(32)
)
BEGIN
     SELECT  user_id, username  FROM  user  WHERE  user.`email` = v_email;
END|

DELIMITER ;

-------
php-code:

$res = mysql_query("CALL select_user_login('$email', '$pw')");

Expected result:
----------------
well, no error ;-)

Actual result:
--------------
MySQL-Error 

1312 - PROCEDURE databsename.select_user_login can't return a result set in the given context )
