hi, guys, I found memory leak using the following code:
#include 
#include 
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();
}
See http://www.boost.org/libs/smart_ptr/weak_ptr.htm. It's specifically 
designed to break these sorts of ownership cycles.
