 1149    CbcSimpleIntegerPseudoCost::!CbcSimpleIntegerPseudoCost (!CbcModel
 * model, int dummy,int iColumn,

 1150                                                            double
 downPseudoCost, double upPseudoCost)

 1151    {

 1152
 !CbcSimpleIntegerPseudoCost(model,iColumn,downPseudoCost,upPseudoCost);

 1153      columnNumber_=iColumn;

 1154    }

 line 1152 should be

   *this =
 !CbcSimpleIntegerPseudoCost(model,iColumn,downPseudoCost,upPseudoCost);

 Otherwise a new object is created and *this is not changed leaving an
 unitialized object.

 This affects stable 2.0 and realease 2.0.0
