Opss, excuse me!

This is the simple program:

#include <iostream>
#include <vector>
#include <boost/pool/pool_alloc.hpp>

using namespace std;

int main()
{
    std::vector<int,boost::pool_allocator&lt;int>> myVector;

    for (int64_t i = 0; i < 150000; ++i)
         myVector.push_back(13);

    boost::singleton_pool<boost::pool_allocator_tag,
sizeof(int)>::release_memory();
    return 0;
}

and this is the valgring output:
