C++ static classes & shared_ptr memory leaks

Question

I can\'t understand why does the following code produce memory leaks (I am using boost::shared_ptr with static class instance). Could someone help me?

Answer 1

At a guess the CRT is reporting a false positive - the following code illustrates that the shared pointer is working correctly, at least with g++

#include 
#include "boost/shared_ptr.hpp"
using namespace std;
using namespace boost;

struct R {
    R() {
        cerr << "ctor" << endl;
    }

    ~R() {
        cerr << "dtor" << endl;
    }
};

struct A {
    static shared_ptr ptr;

    A() {
     ptr =  shared_ptr(new R);
    }

};

shared_ptr A::ptr;
static A a;

int main() {
}

It prints:

ctor
dtor
