The error occurs only if index of array is not present. If delete this
lines of code:

$arrayObj[] = "foo";
$arrayObj[] = "bar";

script work fine.

May be this help you for fix this bug.

Description:
------------
method offsetSet in class extended from ArrayObject crash PHP with
message "PHP has encountered an Access Violation at 018CC7A0"
If method offsetSet not present in Collection class it work fine.

Web-server IIS 5.0 on Windows XP and 6.0 on Windows 2003 Server

Reproduce code:
---------------
class Collection extends ArrayObject
{
        private $data;
        
        function __construct()
        {
                $this->data = array();
                parent::__construct( $this->data );
        }
        
        function offsetGet( $index )
        {
                echo "Collection::offsetGet()\n";
                return parent::offsetGet( $index );
        }
        
        function offsetSet( $index, $value )
        {
                echo "Collection::offsetSet()\n";
                parent::offsetSet( $index, $value );
        }
}

echo "\n\nInitiate Obj\n";
$arrayObj = new Collection();

echo "Assign values\n";

$arrayObj[] = "foo";
$arrayObj[] = "bar";
$arrayObj["foo"] = "bar";

echo "Getting values\n";
echo $arrayObj["foo"];

echo "Printing Collection\n";
print_r( $arrayObj );

echo "Count Collection items\n";
echo count( $arrayObj );


Expected result:
----------------
Initiate Obj
Assign values
Collection::offsetSet()
Collection::offsetSet()
Collection::offsetSet()
Getting values
Collection::offsetGet()
bar
Printing Collection
Collection Object
(
    [0] => foo
    [1] => bar
    [foo] => bar
)
Count Collection items
3

Actual result:
--------------
PHP has encountered an Access Violation at 018CC7A0

Initiate Obj
Assign values
