std::thread thread spun off in object, when does it terminate?

If I spin off an std::thread in the constructor of Bar when does it stop running? Is it guaranteed to stop when the Bar instance gets destructed?

class Bar {

public:

Bar() : thread(&Bar:foo, this) {
}

...

void foo() {
  while (true) {//do stuff//}

}

private:
  std::thread thread;

};
