To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2009-04-21 12:47:21] mailinglists at if-core dot de Description: ------------ The error "zend_mm_heap corrupted" and eventually a "Segmentation fault" error occurs when I try to use bindParam for a parameter which is commented out in the sql statement. The error occurs only and then even not at all times if i use persistent connections I reproduced the error on two servers, both running with PDO_OCI and persistent connections. Reproduce code: --------------- <?php $user_id=1; $dbh = new PDO('oci:dbname=//127.0.0.1:1521/xe;charset=AL32UTF8', 'xx', 'xx', array(PDO::ATTR_PERSISTENT => true)); $dbx = $dbh->prepare(' SELECT id FROM user_data /* ? */ '); $dbx->bindParam(1, $user_id); $dbx->execute(); var_dump($dbx->fetchAll()); ?> Expected result: ---------------- An array with the contents of the Database-Table user_data Actual result: -------------- A blank page and errors in the error_log of the Apache Server. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48037&edit=1
