Std :: Thread Probleme

Ich denke, ich habe eine Art wirklich schlechte Konzepte Probleme. Warum bekomme ich einfach eine Menge Fehler bei der Racebedingungen mit Valgrind. Zuerst dachte ich, dass könnte ein Fehler sein, und ich sah in Foren, dass eine aktualisierte Rolling Release von Linux das lösen wird ... so jetzt habe ich opensuse Tubleweed, 100% aktualisiert. Die folgenden Code Durcheinander haben etwas sehr falsch:Std :: Thread Probleme

#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(); 
}

Wenn ich eine

valgrind --tool=drd ./oncordia

i 5-mal versuchen oder mehr haben und ich bekomme die folgenden Fehler:

@Tudor, die Instanz von FOO als Zeiger passieren haben, das ist warum gibt es '& foo'. Das heißt, ich bin nicht wirklich sicher, was die Frage ist, funktioniert dieser Code wie erwartet? – 111111

@ 111111: Ah ok. – Tudor

Mein cuestion ist, warum ich diese Fehler bekomme? ... Der Code funktioniert wie erwartet – hernanex3

das fabelhafte Handbuch lesen: http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html#debug.races

Der Code ist in Ordnung, valgrind versteht nicht die atomaren Operationen, die wir innerhalb std::shared_ptr verwenden und meldet sie fälschlicherweise als Rennen.

cout ist eine Ressource und sollte mutex-ed (race condition wenn> 1 Faden do_something() oder andere Verwendungen von cout) sein
