Ok, now it work well, thanks!

But..I have another problem. In this code (C++11 with std::tuple)

#include <iostream>
#include <map>
#include <tuple>
#include <boost/pool/pool_alloc.hpp>

using namespace std;

struct data
{
    int a,b;
    char name[50];
    std::map<std::string,std::tuple&lt;uint16_t,uint16_t>> myComplexType;
};

struct myStruct
{
     struct MyOrderTag {};
     typedef boost::singleton_pool<MyOrderTag,sizeof(data)> poolMemory;
};

int main()
{
    data *d = (data*)myStruct::poolMemory::malloc();

    d->a = 8;
    strcpy(d->name,"Hello!");

    //fill myComplexType field (this row causes a segfault!)
    d->myComplexType["one"] = std::tuple<uint16_t,uint16_t>(1,2);

    myStruct::poolMemory::release_memory();
    return 0;
}

I obtain a segmentation fault error when assign a tuple at myComplexType
field. What is wrong?
