If you simply say `x' or `(Bar*)x', then the C compiler + would warn you that type casting incompatible pointer types breaks + strict-aliasing. The solution is to cast to `(void*)' instead which + is the generic pointer type, so the compiler knows that it should + make no strict-aliasing assumption on `x'. But the problem with + `(void*)x' is that seems like in C++, unlike C, `void*' is not a + generic pointer type and assigning `void*' to `Bar*' without a cast + causes an error.
