Description:
------------
when executing the code below, PHP will crash with a segmentation
fault.
Note: To reproduce the crash, the database "test" must exist and
contain a table "user" with an entry with id=1 (or to put it
differently: the query must at least return one result).
Versions of software used:
mysql 5.0.18
php 5.1.6
Reproduce code:
---------------
<?php
class test {
protected static $dbh;
protected function connect() {
self::$dbh = new PDO('mysql:host=localhost;dbname=test', 'test',
'test');
}
public function read($uid) {
self::connect();
$stmt = self::$dbh->prepare("SELECT * FROM user WHERE id =
:uid");
$result = $stmt->execute(array(':uid' => 1));
$rows = $result->fetchAll(PDO::FETCH_OBJ);
var_dump($result, $rows);
}
}
$t = new test();
$t->read(1);
Expected result:
----------------
some error messages, but no segfault
Actual result:
--------------
segmentation fault:
PHP Fatal error: Call to a member function fetchAll() on a non-object
in /home/chris/workspace/testing/crash.php on line 19
