Could you please explain why?

What is your solution for the situation in my original posting? Here it is
again, this time with auto_array:

  foo(unsigned size)
    auto_array<int> result(new int[size]);
    // do something to result
    // if an exception is thrown result will be cleaned up
    return result;

    auto_array<int> foo_result(foo(1000));
    // code is still exception safe

Note that I don't want reference counting overhead (shared_array) or the
overhead associated with std::vector (two pointers instead of just one, default
construction on resize or lots of push_backs, deepcopy semantics).
