My bad, seems it was actually introduced in 4.3.9 by the fix for bug
#29493. Then the question is; if it is a feature or a bug, it certainly
breaks a lot of old unit tests/code for me.

That should read "I belive this bug was backported into PHP 4.3.10", it
seems to be present in the newly released 4.3.10 but not in 4.3.9

I belive this bug was introduced in PHP 4.3.10, it would seem that when
doing EXTR_REFS $a in the example below isn't
SEPARATE_ZVAL_TO_MAKE_IS_REF or something when being extracted from the
array.
Reproduce code:
------------
$a = 1; $b = 1;
$arr = array('acopy' => $a, 'bref' => &$b);
extract($arr, EXTR_REFS);
$acopy++;
$bref++;
debug_zval_dump($a, $b, $arr, $acopy, $bref);
Expected result (As seen on PHP < 4.3.10):
------------
$a: long(1) refcount(2)
$b: long(2) refcount(1)
$arr: array(2) refcount(2){
["acopy"]=>
&long(2) refcount(2)
["bref"]=>
&long(2) refcount(3)
}
$acopy: long(2) refcount(1)
$bref: long(2) refcount(1)
Actual result:
--------------
$a: long(2) refcount(1)
$b: long(2) refcount(1)
$arr: array(2) refcount(2){
["acopy"]=>
&long(2) refcount(3)
["bref"]=>
&long(2) refcount(3)
}
$acopy: long(2) refcount(1)
$bref: long(2) refcount(1)

Reduced reproduce code looks like this:
<?php
$result = extract(array('a'=>1, 'b'=>$foo), EXTR_REFS);
//extract(array('a'=>1, 'b'=>$foo), EXTR_REFS); // they are not the
same
var_dump(array($b));
?>

I have noticed my code output has the wrong indexes.
the expected out put should read index 0 and index 1 not index 'a',
index 'b'
bug still present
