New Comment:
It's hard to explain, but it's expected.
In case the method getName() doesn't declared as "static" it's called
dynamically with current $this (A). This feature is kept for ages for
backward compatibility. You can even see "strict" warning:
Strict Standards: Non-static method B::getName() should not be called
statically, assuming $this from incompatible context in ...
In case you declare getName() "static" you'll get that you expect.

And here is the code:
<?php
namespace A {
class A {
function __construct() {
echo \C\C::getName() . "\n";
}
}
}
namespace B {
abstract class B {
static protected $name = '';
function getName() {
return static::$name;
}
}
}
namespace C {
class C extends \B\B {
static protected $name = 'C';
}
}
namespace {
echo \C\C::getName() . "\n";
$a = new \A\A();
}
?>

Description:
------------
When using static:: in a parent class to refer to the child class that
was called, the keyword is resolved to the caller class instead.
Reproduce code:
---------------
http://olemarkus.com/issue.txt
Expected result:
----------------
I expect both calls to \C\C::getName() to yield the same result:
C
C
Actual result:
--------------
The second one gives the following output:
C
Fatal error: Access to undeclared static property: A\A::$name in
issue.php on line 13
