Also getting "zend_mm_heap corrupted" I'm not the only one having this issue: http://serverfault.com/questions/490061/pdo-odbc-error-just-resets-connection ------------------------------------------------------------------------ [2013-03-21 19:30:18] shrimpwagon at yahoo dot com Description: ------------ I can connect fine. The PDOStatement::fetch method causes a web server connection reset when another method is called after the PDOStatement::execute method and before the PDOStatement::fetch.

Even var_dump($statement) will cause the same problem. $result = $statement->fetch(PDO::FETCH_NUM); Expected result: ---------------- For fetch to not reset connection and return a proper result Actual result: -------------- Server reset. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64483&edit=1
