Bug description: mysqli_bind_result doesn't work with cloned objects
Description:
------------
If you pass to mysqli_bind_result a member variable of an object that will
be cloned and modified multiple times, each modification happens in all
cloned objects, as if they weren't cloned copies, but a single copy of the
object.
Reproduce code:
---------------
<?
/* Say you have a database called 'test' with one table
called 'test' that has one column called 'a' */
$db = new mysqli('localhost');
$db->select_db('test');
$stmt = $db->prepare('SELECT a FROM test');
$stmt->execute();
$result = new stdclass;
// Comment the next line to have the 'right' behaviour
$stmt->bind_result($result->a);
for($i = 0; $i<10; ++$i)
{
$result->a = $i;
$results[] = clone $result;
}
foreach($results as $result)
echo $result->a,"\n";
$db->close();
?>
Expected result:
----------------
0

Actual result:
--------------
9
