 In boost/unordered/detail/hash_table.hpp, line 89-90, there is the
 definition

         template<typename T>
         std::ptrdiff_t const prime_list_template<T>::length = 28;

 I believe 28 should be 40 (the number of primes in
 prime_list_template<T>::value[])...?  Otherwise, it seems resizing your
 hash table past 1.5 million buckets does no good...

 Sorry if this has already been reported, but I couldn't find anything when
 searching the bug tracker.
