Farid Zaripov commented on STDCXX-803:
--------------------------------------
The failing line:
-------------
const std::bitset<N> b (ULONG_MAX & bmask);
-------------
Here bmask type is size_t which equal to unsigned long long.
The possible ways to fix this issue are:
1. cast ULONG_MAX & bmask to unsigned int;
2. add bitset ctor overloads for long long and unsigned long long types.
