Hi Dima,you have choosen M to high, so there will be rounding errors in the solver leading to incorrect results. Possibly, you can solve the problem using exact arithmtic, --exact, or at least check the final solution using exact arithmetic, --xcheck. The first alternative will be slow, so it is most likely better to decrease M.
