Can Derived class static member access protected member from base class?

Can Derived class static member access protected member from base class?

class Base {
protected:
void setvariable(int);
};

class Derived : Base {
public:
static std::auto_ptr<Base> out(new Derived());
out->setvariable(3); // my compiler gives is not accessible error here!
return out;
};

No. Same reasons why it doesn't for a non-static member.
(I'm assuming that all that stuff after public: in Derived
is really in a member function).

Um, isn't the very definition of a protected member that it can
be accessed by classes derived from the base?

I'm thinking the code may well be as seen in OP... :-)

It's a bit more complicated than that. The issue of protected
access and how it sometimes "doesn't work" has been discussed so
many times here and in c.l.c++.moderated that it doesn't really
make sense to begin again.

Mm, never mind, I've spotted my thinko now.
