hi all,

i searched for a similar bug, but i'm not sure, if it has been reported:

the following code compiles fine with gcc, but it shouldn't:

struct foo
{
    friend class caster;
};

struct bar:
    protected foo
{

};

struct caster
{
    foo * cast(bar* b)
    {
        return static_cast<foo*>(b);
    }
};

int main()
{
    bar * b = new bar;
    caster c;
    foo * f = c.cast(b);
}

from my understanding, it should only compile if, caster would be a friend of
bar
