Why can't static_cast a double void pointer?

Question

Consider the following piece of code:

void **v_dptr(nullptr);
int  **i_dptr = static_cast(v_dptr);

The above example produces

Answer 1

I believe this is an XY-problem. Depending on the circumstances it can be solved without reinterpret_cast. If you know that the void** pointer in fact points to a pointer to int, you can safely do this:

int* iptr = static_cast(*v_dptr);

Unless you really need int** in your code. And if you need, you can do:

int** i_dptr = &iptr;

but beware that it will point to a local variable iptr which will be destroyed when goes out of scope.
