================
Comment at: include/__hash_table:140
+    return (__n > 1) ? (size_t(1) << (std::numeric_limits<size_t>::digits - __clz(__n-1))) : __n;
 }
 
----------------
I turned the condition around, and commtted this as r304617:

     return __n < 2 ? __n : (size_t(1) << (std::numeric_limits<size_t>::digits - __clz(__n-1)));
