I just tested this on PHP 4.3.1 and 4.3.2 and it behaves in the same
way, making this a non-critical bug and not related to the foreach
speed-up patch. Assigning to Andi, as he might have a clue why this
happens. The new foreach code is definitely not the problem here.

(The only bug here is that it doesn't give a warning, using $k for both
key and value is not supposed to work!)

I don't think this was ever supposed to work.

Description:
------------
foreach modifies an array, if key and value are the same variable.
see reproduction code.
Reproduce code:
---------------
<?php
$foo = array( 'foo' => 'bar', 'dings' => 'dongs' );
foreach( $foo as $k => $k ) {}
var_dump( $foo );
?>
array(2) {
["foo"]=>
string(5) "dings"
["dings"]=>
NULL
}
Expected result:
----------------
array(2) {
["foo"]=>
string(3) "bar"
["dings"]=>
string(5) "dongs"
}
