Did you remove old php5ts.dll ?
How exactly did you run this code?
What php.exe -v says?
And could you plz try it under some non-MS OS ?

Yes, I load sources this night and built half hour ago
May be CVS issue? Which file check?

Are your sure you tried it with the latest CVS snapshot ?
This issue was fixed about 3 weeks ago and I can't reproduce it with
CVS snapshot of any branches under Linux.

Description:
------------
When I call
array_walk_recursive($array, array('Class', 'static_method1'), 'xxx');
and after it
array_walk_recursive($array, array('Class', 'static_method2'), 'xxx');
static_method2 was not called, but called static_method1

Is it right behavior?

Reproduce code:
---------------
class Test {
    
    public static function rtrim(&$value, $key, $charlist = null) {
        if (is_string($value)) {
            if (null !== $charlist) {
                $value = rtrim($value, $charlist);
            } else {
                $value = rtrim($value);
            }
        }
    }
    
    public static function add_suffix(&$value, $key, $suffix) {
        $value = $value . $suffix;
    }
    
}

$array = array('a' => array('b', 'c'),
               'b' => array('d', 'e'),
               );
array_walk_recursive($array, array('Test', 'add_suffix'), 'xxx');
var_dump($array);
array_walk_recursive($array, array('Test', 'rtrim'), 'xxx');
var_dump($array);

Expected result:
----------------
array(2) {
  ["a"]=>
  array(2) {
    [0]=>
    string(4) "bxxx"
    [1]=>
    string(4) "cxxx"
  }
  ["b"]=>
  array(2) {
    [0]=>
    string(4) "dxxx"
    [1]=>
    string(4) "exxx"
  }
}
array(2) {
  ["a"]=>
  array(2) {
    [0]=>
    string(7) "b"
    [1]=>
    string(7) "c"
  }
  ["b"]=>
  array(2) {
    [0]=>
    string(7) "d"
    [1]=>
    string(7) "e"
  }
}

Actual result:
--------------
array(2) {
  ["a"]=>
  array(2) {
    [0]=>
    string(4) "bxxx"
    [1]=>
    string(4) "cxxx"
  }
  ["b"]=>
  array(2) {
    [0]=>
    string(4) "dxxx"
    [1]=>
    string(4) "exxx"
  }
}
array(2) {
  ["a"]=>
  array(2) {
    [0]=>
    string(7) "bxxxxxx"
    [1]=>
    string(7) "cxxxxxx"
  }
  ["b"]=>
  array(2) {
    [0]=>
    string(7) "dxxxxxx"
    [1]=>
    string(7) "exxxxxx"
  }
}
