Using uppercased occurs memleaks though. (probably related to #47414) Reproduce code: --------------- <?php $db = new PDO('firebird:dbname=...', 'sysdba', 'foo'); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); @$db->exec('drop table test'); $db->exec('CREATE TABLE test(idx int NOT NULL PRIMARY KEY, txt VARCHAR(20))'); $db->exec('INSERT INTO test VALUES(0, \'String0\')'); $stmt = $db->prepare('SELECT idx, txt FROM test ORDER by idx'); $idx = $txt = 0; $stmt->bindColumn('idx', $idx); $stmt->bindColumn('txt', $txt); $stmt->execute(); $stmt->fetch(PDO::FETCH_BOUND); Actual result: -------------- Program received signal SIGSEGV, Segmentation fault.
