New Comment:
This patch seems to be much more serios. I found that when I was using
foreach($arr as $value), instead of receiving a value in $value, I was
getting a strange array, which broke my script (while foreach($arr as
$key => $value) was working fine). Unfortunately I can't tell you
exactly what was happening, as my hoster operatively returned 4.3.9
back...

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.

Cangelog:
"Backported Marcus' foreach() speedup patch from PHP 5.x."
How I can remove this patch ?
For example doesn't work Smarty.

foreach( $foo as $k => $k ) {}
var_dump( $foo );
?>
array(2) {
["foo"]=>
string(5) "dings"
["dings"]=>
