#include <iostream>

class RefCountImpl
{
private:
//data members
protected:
void operator delete(void*) { ::delete this };
public:
void Kill() { delete this; }
//methods};
};

int main()
{
RefCountImpl Foo;
RefCountImpl* Bar = new RefCountImpl;
Bar->Kill(); // Works
delete Bar; // Doesn't work

return 0;

}

Show how you are trying to use it. It does not fail for me unless I try to
delete the instance, are you trying to do this? Are you trying to make it
on the stack? How are you using it? Show the code that is actualy causing
the error when you compile.
