Description:
------------
spl_autoload_register does not work with lsb/get_called_class()

Reproduce code:
---------------
namespace test;
class A {
	static function test($v='') {
		var_dump(get_called_class());
	}
}
class B extends A {
}
B::test();
spl_autoload_register(__NAMESPACE__.'\B::test');
new X();

Expected result:
----------------
string(6) "test\B"
string(6) "test\B"

Fatal error: Class 'test\X' not found in ... on line ...

Actual result:
--------------
string(6) "test\B"
bool(false)

Fatal error: Class 'test\X' not found in ... on line ...
