Consider the following piece of code:

std::string s;
std::cin >> s;

Assume that memory is so low and the string is so long
that a bad_alloc exception occurs during the string input
(e.g. by some string::operator+=() ).

What should the state of std::cin be after the operation?
bad() or fail()?
I did not find any information in 21.3.7.9,
is this covered elsewhere in the standard?
