Thread: derived class can not access base class protected member?

Hello everyone,


I met with a strange issue that derived class function can not access base class's protected member. Do you know why?

Here is the error message and code.

Code:

error C2248: 'base::~base' : cannot access protected member declared in class 'base'

Code:

class base
{
protected:
	~base() {}
private:
	void foo()
	{
		base* b = new base;
		delete b;
	}
};

class derived : public base
{
public:
	~derived() {}
private:
	void goo()
	{
		base* b = new derived;
		delete b; // error in this line
	}
};

thanks in advance,
George
