I thought &*vector::end() was undefined behavior... until I saw some post refer to Stroustrup's code:

void vector_pointer_test(element_t* first, element_t* last, int number_of_times) 
{ 
       vector<element_t> container(first, last); 
       // &*container.begin() gets us a pointer to the first element 
       sort(&*container.begin(), &*container.end()); 
       unique(&*container.begin(), &*container.end()); 
}

Is dereferencing an end() iterator undefined behavior, or is it valid?
