Comment:

 The weights are not negative in this testcase - the probs array is
 actually printed out. Please run the testcase. It offsets them so that
 they become non-negative.

 For negative weights, such a normalization should be done within boost
 anyway I think, but then the special value would have to be -infty instead
 of 0 to give probability 0, which is an API change.
