Hi, all:

    I am currently making modification in file PositionOrientationRecorder.hpp 
and PositionOrientationRecorder.cpp and I am doing a very simple operation on 
PositionOrientationRecorder.hpp, which is add several variables:

public:
Real sumKinematicEnergy, deltaKinematicEnergy, prevKinematicEnergy;
Vector3r maxUnbalForce;

which will make the PositionOrientationRecorder.hpp look like:
///====================================================================
class PositionOrientationRecorder : public DataRecorder
{
	public :
		std::string outputFile;
		unsigned int interval;

		std::ofstream ofile;
                ///here in the previous version, it said FIXME???
        public:
                Real sumKEnergy, prevKEnergy;
                Vector3r maxUnbalForce;

		PositionOrientationRecorder ();
		~PositionOrientationRecorder ();
		virtual void action(Body* b);

	protected :
		virtual void postProcessAttributes(bool deserializing);
		void registerAttributes();
	REGISTER_CLASS_NAME(PositionOrientationRecorder);
	REGISTER_BASE_CLASS_NAME(DataRecorder);
};
///====================================================================
however after compile and install, use the filegenerator, select 
SDECSpheresPlane, generated a scene.xml file, YADE prompted a message "file 
scene.xml" generated successfully" but after I clicked OK bottom, the YADE 
crashes and gives a whole bunch of errors:

===Aborted

I tried several times and after commented the std::ofstream ofile, it seems I 
can add more variables to the class, however, seems after adding 7 variables, 
the program will crash anyway, but if you add less than 7 variables, the glic 
error will not occur.
I have met this problem several times and I am not sure it is due to the QT 
GUI or any other problems, although I don't know whether this error is 
repeatable for others but any kind of help is welcome!

Thanks a lot!
