The following simple code snippet is correctly rejected by versions 2.95 and
3.2, but is accepted by 3.3:


class A
{
public:
    int operator()(int i) const { return 0; }
};

class B
{
private:
    A a;
};

int main()
{
        return B().a(0);
}



This happens with both const and non-const operator(), but doesn't seem to
happen with other operators. I tried += and operator[], which both correctly
generated errors.
