#include <future>
#include <iostream>
#include <string>

using std::cout;
using std::endl;

int main()
{
    try
    {
        std::future<int> f;
        f.get();
    }
    catch(const std::future_error& ex)
    {
        auto what1 = ex.what();

        std::string str="123";
        str.reserve(20);

        if(str.data() == what1)
            cout << "impossible" << endl;
    }
}

--------------------------
this program print:

impossible

but it should print nothing, I have no bugzilla account, this mail is
all I can do;


and, forgive me poor english
