I have fully not grasped for which T the specializations of
__has_contiguous_iter are intended to be used, but given the fact that
+ template<typename _Tp, typename _Alloc>
+ struct __has_contiguous_iter<std::vector<_Tp, _Alloc>>
+ : std::true_type
+ { };
exists I think you really want to exclude any vector<bool, Allocator>
by additionally adding
+ template<typename _Alloc>
+ struct __has_contiguous_iter<std::vector<bool, _Alloc>>
+ : std::false_type
+ { };
