Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is the only way we can bypass limitations of the MySQL's prepared statement interface. If you disable native prepared statements this problem will go away.
