[Bug c++/38557] New: dynamic_cast should give a warning/error for non related classes

[Woebbeking at web dot de]

Hi,

in this example

struct A
{
    virtual ~A() {}
};


struct B
{
    virtual ~B() {}
};


int main()
{
    A* a(0);

    dynamic_cast<B*>(a);
    static_cast<B*>(a);

    return 0;
}

the static_cast gives an error but the dynamic_cast not even a warning.


Cheers,
André
