Here is a self contained testcase for this:
struct B1
{
    virtual ~B1 () throw(){}
    B1 (){}
    int x;
};
struct B2
{
    virtual ~B2 () throw(){}
    B2 (){}
    int x;
};
struct D : B1, B2
{
    D (){}
    ~D () throw(){}
    int y;
};
void f1 (D*);
void f2 (B2*);
void f3 (B1*);
int main (void)
{
    f1 (::new D);
    f2 (::new D);     
    f3 (::new D);
}
void f1 (D* p) { ::delete p; }
void f2 (B2* p) { ::delete p; }  
void f3 (B1* p) { ::delete p; }

With gcc, I get:
free(): invalid pointer 0x9317010!
