Description:
------------
Tested on php5.3.0-alpha3 (must be tested on last snap)

When calling parent class method, self is responding

(sorry for my bad english)

Reproduce code:
---------------
class base
{
	public function __call($name, $arguments)
	{
		echo get_called_class() . "->$name() is called \n\n";
	}
}


class A extends base
{
	public function parent_automatic()
	{
		$parentclass = get_parent_class($this);
		echo get_class($this) . '->'. __FUNCTION__ ."() call $parentclass::test() \n";
		$parentclass::test();
	}
	
	public function parent_manual()
	{
		echo get_class($this) . '->'. __FUNCTION__ ."() call A::test() \n";
		A::test();
	}
}


class B extends A {}



$b = new B;
$b->parent_automatic();
$b->parent_manual();


Expected result:
----------------
B->parent_automatic() call A::test() 
A->test() is called 

B->parent_manual() call A::test() 
A->test() is called 


Actual result:
--------------
B->parent_automatic() call A::test() 
B->test() is called 

B->parent_manual() call A::test() 
B->test() is called

class base
{
	static public function __callstatic($name, $arguments)
	{
		echo get_called_class() . "::$name() is called \n\n";
	}
	public function __call($name, $arguments)
	{
		echo get_called_class() . "->$name() is called \n\n";
	}
}



give the same result.
but without "__call()", it's ok.

if "$this" exists in inheritance, "__call()" (of $this) is called instead of "__callstatic()"

Thank you for your bug report.

Are you sure the behavior you describes is not documented? Please take a look at:
http://nl.php.net/manual/en/language.oop5.late-static-bindings.php#language.oop5.late-static-bindings.edge-cases

Yes, it's documented :
"it might give unexpected results in so-called edge cases"

I see two problems :
- self class respond
- "__call()" is called instead of "__callstatic()"

There is not means to solve that ?

That is because the call is not static. $name::method() is not sufficient to garantee a static call:
- the target method has to be static or 
- the current scope has to be void

In your case, the definition of the target method is not explicit, as test() is not defined and you have both __call and __callStatic. Since the current scope exists, it will use __call by default.
