No, I've already explained why.
No bug here.

Ok. So there must be another way to get static variable than self::$var
to enable inherited methods that use static variables in subclasses?
On the otherhand shouldn't private static be only defined in ongoing
class. In the case of instance class D shouldn't it actually print 2
from $D->show() since the method is inherited and private static is
redefined?

"self" (as well as "parent") is resolved in compile time, so it'll
always point to the class where it was used.
This is expected behaviour.

Description:
------------
self:: doesn't care for inheritance in instantiated classes.
self:: doesn't care for private.
private & static keywords don't work together.
redeclaration of static variables doesn't work even for private static.
Reproduce code:
---------------
<?php
class A {
static $a = 1;
function show() {
echo self::$a;
}
}
class B extends A {
static $a = 2;
}
B::show(); // writes "1" not "2"
$b = new B();
$b->show(); // writes "1" not "2"
print '<hr />';
class C {
private static $a = 1;
function show() {
echo self::$a;
}
}
class D extends C {
private static $a = 2;
}
D::show(); // writes "1" not "2"
$d = new D();
$d->show(); // writes "1" not "2"
?>
Expected result:
----------------
22<hr />22
Actual result:
--------------
11<hr />11
