People are wrong then. Trust me, I work enough with ill-conditionned problems, including SVDs, to know that the algorithms are not deterministic. You can improve them by controlling the random starting point, but in many case it is not enough. Decreasing the tolerance on the algorithm may help (I don't know if we can control that with the lapack interface), but at the cost of a lot of computing time.
