std :: проблемы с потоком

Я думаю, что у меня проблемы с плохой концепцией. Почему я просто получаю много ошибок условий гонки с valgrind. Сначала я подумал, что это может быть ошибка, и я видел на форумах, что обновленная версия релиза Linux решит это ... так что теперь у меня есть openuse tubleweed, 100% обновленный. Следующий мусс кода имеет что-то очень неправильно:std :: проблемы с потоком

#include <iostream> 
#include <thread> 

using namespace std; 

class FOO 
{ 
public: 
    void do_something() 
    { 
     cout<<"cout somethin\n"; 
    } 
}; 

int main() 
{ 
    FOO foo; 
    std::thread t (&FOO::do_something,&foo); 
    t.join(); 
}

Когда я сделать

valgrind --tool=drd ./oncordia

я должен попробовать 5 или более раз, и я получаю следующие ошибки:

@Tudor, вы должны передать экземпляр FOO как указатель, который почему существует '& foo'. Тем не менее, я на самом деле не уверен, в чем вопрос, работает ли этот код так, как ожидалось? – 111111

@ 111111: А, ок. – Tudor

Мой вопрос: почему я получаю эти ошибки? ... Код работает как ожидалось – hernanex3

Читать сказочным руководство: http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html#debug.races

код ОК, Valgrind не понимает атомарные операции, которые мы используем внутри std::shared_ptr и неправильно передает их в качестве гонок.
