All other queries work well. The bug is reproducible only on some versions of Windows - in this case - Windwos Server 2003. Reproduce code: --------------- <?php $connection = new PDO('mysql:host=localhost;dbname=dbName', 'theUser', 'thePassword'); $query="SHOW COLUMNS FROM someTable"; $result = $connection->query($query); var_dump($result); ?> Expected result: ---------------- Apache crashes - the service is stopped because of too many errors. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47722&edit=1
