hi, guys, I found memory leak using the following code:

#include <boost\array.hpp>
#include <boost\shared_ptr.hpp>
using namespace boost;

class C
{
public:
    shared_ptr<C> pNext;
};

void test()
{
    shared_ptr<C> c0(new C());
    shared_ptr<C> c1(new C());
    c0 -> pNext = c1;
    c1 -> pNext = c0;
}

void main()
{
    test();

    _CrtDumpMemoryLeaks();
}

when running with F5, it said:

Detected memory leaks!

Any body have an idea about this? Thanks very much.
