std::thread problema
« en: 16 Mayo 2012, 14:13 pm »
Hola gente tengo un pequeño probrlma con el std::thread, este es mi siguiente codigo

Código
  1.     #include <iostream>
  2.     #include <thread>
  3.  
  4.     using namespace std;
  5.  
  6.     class FOO
  7.     {
  8.     public:
  9.     	void do_something ()
  10.     	{
  11.     		cout<<"cout somethin\n";
  12.     	}
  13.     };
  14.  
  15.     int main ()
  16.     {
  17.     	FOO foo;
  18.     	std::thread t (&FOO::do_something,&foo);
  19.     	t.join();
  20.     }

Cuando hago un

Código
  1.     valgrind --tool=drd ./oncordia

donde oncordia se llama mi ejecutable. Ejecuto varias veces ese comando hasta que en una oportunidad obtengo:
