>Description:
If traits_type::int_type is not convertible to char_type, operator>>(basic_istream, basic_string) fails to compile.
This is because the implementation of this function passes an object of type int_type to ctype::is, this is a serious error also when int_type is int and char_type is char if char is signed.
