What will be the result of C++ code?

Question

#include <iostream>
#include <memory>
#include <vector>
#include <algorithm>
#include <functional>
using namespace std;
// gcc -o test-1 test.cpp /usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.3.2/libstdc++.so

class A {
int fvalue;
static int ginstance_count;
public:
A() : fvalue(0)
{
++A::ginstance_count;
cout << "A::A()" << endl;
}
~A()
{
--A::ginstance_count;
cout << "A::~A()" << endl;
}
static void leakReport()
{
cout << ginstance_count << " instances alive" << endl;

Answer 1

Entering the block (using for_each)
A::A()
A::A()
A::A()
List::~List result: 3 instances alive
Left the block
Entering the block (well-working code)
A::A()
A::A()
A::A()
A::~A()
A::~A()
A::~A()
List::~List result: 3 instances alive
Left the block
