Description:
------------
PHP does not throw E_DEPRECATED exception when non static method calls as static inside object.

Test script:
---------------
<?php

class Foo {
    public function bar()
    {
        echo "1";
    }
    public function bar2()
    {
        static::bar();
    }
}

$class = new Foo();

//throw E_DEPRECATED
$class::bar();
//!!! no exception
$class->bar2();

Expected result:
----------------
I expect 2 E_DEPRECATED

Actual result:
--------------
$class::bar() - throw Exception
but $class->bar2() - work without exception

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

"static::bar()" does not mean to call the bar method statically. Rather the "static" indicates the use of late static binding (LSB) and means to call the bar method of the class which was originally invoked. Just like how "self::" means to call a method on the class currently executing, or "parent::" on the superclass.

See example #3 in the documentation for late static binding.
