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.
