Comment (by mgalati):
I think you can safely change that to :
if(m_status != STAT_INFEASIBLE)
to force user heuristics to be called even when no cuts/cols are added. I
think that was just for efficiency - as when nChanges=0, that would
normally mean you are done with processing that node.
Try removing that condition.
