5767,A bug in seeding with sequence in Mersenne Twister,Synge Todo <wistaria@…>,Steven Watanabe,"There is a bug in boost/random/mersenne_twister.hpp:
{{{
   176          // fix up the state if it's all zeroes.
   177          if((x[0] & (~static_cast<UIntType>(0) << r)) == 0) {
   178              for(std::size_t j = 1; i < n; ++j) {
   179                  if(x[j] != 0) return;
   180              }
}}}
Since there is a typo in line 178 (""i < n"" should be ""j < n""), x[0] will always be reset to some constant (static_cast<UIntType>(1) << (w-1)).
