Tamas,

I find it very surprising that your breakpoint in the destructor is not
being hit at all. This:
    #include <boost/smart_ptr/shared_ptr.hpp>
    #include <iostream>
    struct D {
        ~D() {
            std::cout << "~D\n";
        }
        template<class U>
        void operator()(U*) { 
            std::cout << "operator()\n";
        }
    };
    struct T { };
    int main()
    {
        {
            auto p = boost::shared_ptr<T>(new T, D{});
            std::cout << "...\n";
        }
    }

Outputs:
    ~D
    ~D
    ...
    operator()
    ~D
