Please, this is definitely bug from GCC, for same code give me error in Visual
Studio 2008 but not in GCC:

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <memory>
using namespace std;
class A{
public:
  A() : p(new int(10)){
  }
  const auto_ptr<int> p;
};
int main() {
  A a;
  printf("a pointer=0x%x\n", a.p.get());
  A a2 = a;
  printf("a pointer=0x%x\n", a.p.get());
  printf("a2 pointer=0x%x\n", a2.p.get());
  return 0;
}

Error:

Error   1       error C2558: class 'std::auto_ptr<_Ty>' : no copy constructor
available or copy constructor is declared 'explicit'      c:\documents and
