11769	64-bit hash_combine has weakness against zero input	Andrey Semashev	Daniel James	The `hash_combine_impl` function for 64-bit `size_t` (see [https://github.com/boostorg/functional/blob/develop/include/boost/functional/hash/hash.hpp#L237 here]) does not have an additive component. As a result, hashing strings of zeros always results in zero hash value regardless of the length of the string.	Bugs	closed	To Be Determined	hash	Boost Development Trunk	Problem	fixed
