8133	multiprecision, failed gcd  tests (test_cpp_int.cpp)	Stepan Podoskin <stepik-777@…>	John Maddock	"I modified test_cpp_int.cpp to generate random numbers with a lot of ones or zeros. 

I modified '''T generate_random(unsigned bits_wanted)''':
{{{

   ...
   T val = 0;
   for(unsigned i = 0; i < terms_needed; ++i)
   {
      val *= (gen.max)();
      switch (gen() % 5)
      {
      case 0:
          val += gen();
          break;
      case 1:
          val += 1;
          break;
      case 2:
          val += (gen.max)() - 2;
          break;
      case 3:
          val += (gen.max)() - 1;
          break;
      }
   }
   val %= max_val;
   return (val == 0)? val : 1;
}

}}}

This caused some tests related to gcd computation to fail. Here is output (I removed some parts of it with results of operations) - http://pastebin.com/iZdmX1bq"	Bugs	closed	To Be Determined	multiprecision	Boost 1.53.0	Problem	fixed
