I don't understand the need for this one.
- an empty class with just one virtual function (normally the same
size as a pointer)
Sometimes names can be deceptive :)
class empty_abstract_class { virtual int member(); };
C++ in fact forbids cast from a regular pointer to a member
selector (or the other way).
Actually from/to any pointer to member. (I was corrected recently on the definition of pointer to member)
My conclusion is, you can nearly always assume the size of a data
pointer is the same as a function pointer.
In a Posix compliant world this is a guarantee and it is required by dlsym.
