I have a small quiz:
Here is a small code, compiled with “/clr” (this is important).
Can you tell me, what is the exact callstack inside the method “Foo”?
(And how can you prove this)

struct V
{
  V() {}
  V(const V &v) 
  {
    this->i = v.i;
  }
  int i;
};

class C
{
public:
  void CallFoo()
  {
    V v;
    Foo(v);
  }
  virtual void Foo(V v)
  {
    // TODO: What is the callstack!?
  }
};

int main()
{
  C c;
  c.CallFoo();
}

Any hints can be posted as comments.
By the way: VS208 does not show you the exact callstack, but it gives you a hint, that there is something that you do not see 😉
