In the following short C++ program,

// test use of "protected" members

class bottom
{
protected:
	int	botint;

public:
	int	getbot() { return botint; }
};

class higher : public bottom
{
protected:
	float	hifloat;

public:
	float	gethi() { return hifloat; }

friend void	mumble(higher&);
};

main()
{
	higher	bar;

	mumble(bar);
}

void mumble(higher& foo)
{
	foo.hifloat = 2.718;	// this is OK
	foo.botint = 3;		// should this be allowed?
	return;
}

Oasys C++ rel. 1.2 complains:

	... error: botint is protected

Is the complaint valid?  If so, why?
