I can reproduce a crash with:
<?php
class MyObjet implements ArrayAccess
{
public function __construct() { }
public function offsetSet($offset, $value) { }
public function offsetExists($offset) { }
public function offsetUnset($offset) { }
public function offsetGet ($offset) {
return function () { };
}
}
$a = new MyObjet();
echo $a['p']('foo');
?>

Description:
------------
Closures cant use variables from external context when the context is in
ArrayAccess method
Test script:
---------------
<?php
class MyObjet implements ArrayAccess
{
// All the stuff for ArrayAccess
public function offsetGet ($offset)
{
return function ($var) use ($offset) { // here is the problem
return sprintf('<%s>%s</%$1s>', $offset, $var);
};
}
}
$a = new MyObjet();
echo $a['p']('foo');
Expected result:
----------------
<p>foo</p>
Actual result:
--------------
PHP Notice: Undefined variable: offset in {file.php} on line 11
