Tested with g++ versions 4.1.2 and 4.3.2, they both fail to reject the
following invalid code:
class E {
int x;
class B { };
class I {
B b; // error: E::B is private
int y;
void f(E* p, int i)
{
p->x = i; // error: E::x is private
}
};
int g(I* p)
{
//return p->y; // error: I::y is private (g++ correctly errors here)
}
};
This is taken straight from the standard, section 11.8.1:
http://www.csci.csusb.edu/dick/c++std/cd2/access.html
1 The members of a nested class have no special access to members of an
enclosing class, nor to classes or functions that have granted friend-
ship to an enclosing class; the usual access rules (_class.access_)
shall be obeyed. The members of an enclosing class have no special
access to members of a nested class; the usual access rules
(_class.access_) shall be obeyed. [Example:
class E {
int x;
class B { };
class I {
B b; // error: E::B is private
int y;
void f(E* p, int i)
{
p->x = i; // error: E::x is private
}
};
int g(I* p)
{
return p->y; // error: I::y is private
}
};
--end example]
