Re: Problem with Copy Constructor and overloaded assignment operator with templates

Hi everyone,

I'm writing a class that inherits from std::vector in order to add
some additional functionality. I'm having a compiler problem, however,
when I have a function that returns this class. I've drilled down and
been able to create a very simple example of the problem. Here's my
code:

<code>
#include <vector>
#include <iostream>

using std::vector;
using std::cout;
using std::endl;

template <typename T>
class B : public std::vector<T>
{
public:
  B(){ cout << "In B ctor" << endl; }

  B(B<T> &b) { cout << "In B copy ctor" << endl; }

  B<T>& operator=(const B<T> &b) { cout << "In B assign." << endl;
return *this; }

  ~B(){ cout << "In B destructor" << endl; }

};

B<int> test()
{
  B<int> returnVal;
  return returnVal;

}

int main()
{
  B<int> b;
  b = test();
