Your "copy constructor" is not an appropriate copy constructor.

Change it to:

A(A const& a)
{
  cout << "copy constructor" << endl;
}

Also, your assignment operator is not an appropriate assignment operator.

Change it to:

A const& operator = (A const& a)
{
  cout << "= operator" << endl;
  return *this;
}
