 New Comment:

To my knowledge array_diff* do not unset anything. I confirm the
behaviour under 5.1.0-dev (of 7.Aug.2004) as well as with 4.2.3 (so
this problem exists also in the old implementation of the function).
The problem appears when only $GLOBALS is used, and the latter is a
variable (array) with specific behaviour. Unfortunately I wasn't able
to reproduce similar problem with one of the other array functions.

last win snapshot
<?php
error_reporting(E_ALL);
$zz = $GLOBALS;
$ff = 'ff';
array_diff_assoc($GLOBALS, $zz);
var_dump($zz); // this line crashes apache when optimizer is running
?>

when optimizer is disabled gives the following notice message and
doesn't crash

Notice: Undefined variable: zz in c:\wwwww\test\crashme.php on line 7
NULL 

seems like array_diff parameters are being unset inside the function

Description:
------------
when using array_diff with one of the parameters is $GLOBALS seems like
the whole variable scope is messed up. 


Reproduce code:
---------------
<?php
$zz = $GLOBALS;
$gg = 'afad';
var_dump(array_diff_assoc($GLOBALS, $zz));
echo $gg; // strange behavour. $gg is like an array!!!
// var_dump($gg); // this call fails apache
?>

Expected result:
----------------
expect seeing 'afad' and empty array;

Actual result:
--------------
array(0) { } Arra

the length of "Arra" string depends on the length of $gg length;

if uncomment the last line - apache child fails
[Mon Jul 19 10:26:00 2004] [notice] child pid 10946 exit signal
Segmentation fault (11
