[Boost-users] shared_array double free problem

22 Jul 2005

      Here is the compilable code:
#include <boost/shared_array.hpp>
#include <iostream>

template <typename T> class VectorView;
template <typename T>
inline std::ostream& operator << (std::ostream& os, const VectorView<T>& VOut)
{
    os<<VOut.size()<<std::endl;
    for (int i=0; i<VOut.size() && os.good(); ++i){
	os<<VOut(i)<<"";
	os<<std::endl;
    }
    return os;
}

template<typename T>
class VectorView
{
private:
  int _size;
  boost::shared_array<T> _vp;
public:
  VectorView(T* ptr, int size)
  {
    _size=size;
    _vp=boost::shared_array<T>(ptr);
  }
  T operator () (int pos) const
	    {
		return _vp[pos];
	    }
 int size() const
    {
	return _size;
    }
  ~VectorView()
  {
  }
};

int main (void)
{
  double a[]={1,2,3,4,5,6,7};
  VectorView<double>V(a,4);
  std::cout<<V;
  return 0;
}

Any workaround?
