If an operator is overloaded for a C++ class how could I use a default operator instead?

Question

_com_ptr_ has an overloaded operator&() with a side effect. If I have a variable:

_com_ptr_t variable;

How could I ret

Answer 1

I've seen this case pop up in an ISO meeting as it broke some offsetof() macro implementations (LWG 273). The solution: &reinterpret_cast<unsigned char&>(variable)

Answer 2

&variable.GetInterfacePtr();

Answer 3

I define this utility function:

template<typename T>
T *GetRealAddr(T &t)
    { return reinterpret_cast<T*>(&reinterpret_cast<unsigned char &>(t)); }
