 Description   

Copy without assign

This class has a user-defined copy constructor but no user-defined assignment operator. If the copy constructor is necessary to manage owned resources then a corresponding assignment operator is usually required. If an object of this type is assigned memory leaks and/or use-after-free errors may occur. Note that a compiler-generated assignment operator will perform only a bit-wise copy for any fields that do not have their own assignment operators defined. Class has user-written copy constructor but no user-written assignment operator
