 New Comment:

In addition to the above description I would like to add that the
sub-classes CAN access each other's protected variables, if the
accessing is done in a shared parent class.

Description:
------------
In class structures where the sub-classes are extended non-linearly
(i.e. multiple classes on the same tier), the sub-classes in different
lines cannot access variables defined as protected in a shared parent
class in eachother.

Reproduce code:
---------------
http://pastebin.com/683438

Expected result:
----------------
Tier3A accessing Tier3C...
OK! ('Value from Tier3C')
Tier3B accessing Tier3C...
OK! ('Value from Tier3C')


Actual result:
--------------
Tier3A accessing Tier3C...
OK! ('Value from Tier3C')
Tier3B accessing Tier3C...

Fatal error: Cannot access protected property Tier3C::$value in
protected.php5 on line 31
