I'm not sure this is a problem. I ran the same test and as you say, it
dynamically created a new variable with local scope to the derived (child)
class. I would expect this to happen as it can not access private members
of its base (parent) class.
In your statement:
"But when trying to access this value from the parent class, it is not
there."
Well it shouldn't be. A base class does not know anything about its
derived class's members or methods. Inheritence doesn't work in that
direction. Only derived classes know about their base class members or
methods.
