New Comment:
Yeah, you're right it works fine in 5.1.4, but new arginfo causes this
in 5.2.
Hannes, are you sure arginfo for array_key_exists() is correct? I don't
see any reasons to use references there, though.
This patch fixes it for me:

Description:
------------
Values returned by ArrayAccess::offsetGet() cannot be used as a search
key in a call to array_key_exists(). It looks like for some reason the
scripting engine requires that the first argument of array_key_exists()
is writable, which conflicts with the documented prototype of
array_key_exists().
The sample code works fine with PHP 5.1.4 so it is a problem introduced
in PHP 5.2.
Reproduce code:
---------------
<?php
class array_obj implements ArrayAccess
{
public function offsetExists ($index) {return (true);}
public function offsetGet ($index) {return (5);}
public function offsetSet ($index, $value) {}
public function offsetUnset ($index) {}
}
$obj = new array_obj ();
array_key_exists ($obj [0], array ("a", "b", "c"));
?>
Expected result:
----------------
The program should terminate with no output at all.
Actual result:
--------------
Fatal error: Objects used as arrays in post/pre increment/decrement
must return values by reference in /archive/error.php on line 14
