void f0(int = 5) {}
void f1(int = 2) {}
void f_(int) {}
                                                                               
                      
template<typename T>
void back_forth(T * y) {
  reinterpret_cast<T *>(reinterpret_cast<void (*)()>(y))();
}
                                                                               
                      
int main() {
  //back_forth(f_); //fails!
  back_forth(f0);
  back_forth(f1);
  back_forth(f_); //succeeds!
}

In addition, the call to f1 inside back_forth(f1) thinks the argument is 5, not 2.

This is a dup of bug 4205, the reinterpret_cast is not needed.
