If anything is strange, it's that copy constructor invocation and assignment operator invocation look similar. However, it's not all that surprising either. In the first case, an object is being constructed. In the second case, it's not. C++ creates four methods for you automatically in any empty class. Any class with bare pointers should probably have its own implementation for all four. There is nothing at all strange or unpredictable about assignment in this case.
