--- Comment #3 from Thomas Huxhorn <thomas.huxhorn at web dot de> ---
Here is another one:

class C {
public:
   ~C() {} // comment out to trigger warning at c.noWarning()

  int giveWarning()  __attribute__((warn_unused_result)) { return 0; }
  C noWarning()  __attribute__((warn_unused_result)) { return C(); }
};

int main() {
    C c;
    c.giveWarning();
    c.noWarning();
   return 0;
}


A workaround for me is to delete the empty deconstrcutor. But thats not always
possible :/
