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.
