Interesting. I had no idea that feature existed. Just checked with 5.5.6 and it has the same
behavior.
Looks like a bug then as it's not showing any class at all. However I'm not sure which
class it should show: could be A if it resolved as B::parent's who, or it could be B if it
resolved as B and then parent::who.

According to
http://us1.php.net/manual/en/language.types.callable.php
It is valid:
// Type 5: Relative static class method call (As of PHP 5.3.0)
class A {
public static function who() {
echo "A\n";
}
}
class B extends A {
public static function who() {
echo "B\n";
}
}
call_user_func(array('B', 'parent::who')); // A

array('B', 'parent::who') is not valid: the second element must be the name of a
method. array('B', 'who') is the correct form.

Description:
------------
---
From manual page: http://www.php.net/function.get-called-class
---
B::who(); should has the same result as call_user_func(array('B',
'parent::who')); But it's not.
See the example below.
Test script:
---------------
<?php
class A
{
public static function who()
{
var_dump(get_called_class());
}
}
class B extends A
{
public static function who()
{
parent::who();
}
}
B::who();
call_user_func(array('B', 'parent::who'));
?>
Expected result:
----------------
string 'B' (length=1)
string 'B' (length=1)
Actual result:
--------------
string 'B' (length=1)
boolean false
