preprocessed code

Command line: c++ -std=c++0x -save-temps bug1.cpp
Code:

#include <vector>
/*#include <iostream>*/

#if false
class V : public    std::vector<int>
#else
class V : protected std::vector<int>
#endif
{
public:
  void echo(){for(int x:*this) /*std::cout << ' ' << x */ ;};
};


int main()
{
    V a;
    a.resize(20);
    a.echo();
}

Change false to true in #if directive and code will be compiled succesfully.
