[Bonmin] Last solution not being saved

Hello everybody,

I've been using bonmin through its ampl interfase. I've noticed that when
the solver ends with an infeasible problem, the values of the variables are
not updated, (i.e., the values of the returned variables are the same as the
initial values I supplied). I was wondering if this is normal behavior or if
there is a way to get the last feasible (NLP) solution calculated.

I'm using the BB method...  Although I've seen this behavior with the other
methods as well.

Thanks all,
  Rodrigo.
