Summary: shared_ptr<> causes memory leacks and crash

Initial Comment:
I have written this small test to reproduce the bug.
Please see..

#include <cstddef>
#include <boost/shared_ptr.hpp>
#include <boost/test/unit_test.hpp>

using namespace std;
using namespace boost;
using namespace boost::unit_test_framework;

  class A;

  class B
  {
  public:
    B(boost::shared_ptr<A> ptr) : ptr_(ptr) {}
    ~B() {}

  private:
    boost::shared_ptr<A> ptr_;
  };

  class A
  {
  public:
    A(int value) : value_(value) {}
    ~A() {}

  private:
    int value_;
  };

void test_shared_ptr()
{
  BOOST_CHECKPOINT("Testing shared pointer...");

  shared_ptr<A> a1(new A(10));

  {
    shared_ptr<B> b1 = a1->create();
  }

  {
    shared_ptr<B> b1 = a1->create();
  }
}
