[ROOT] Segmentation Violation when using new ROOT version

Hi,

I have a problem with running compiled code with the new root version
3.01, from July 24 2001. I receive a segmentation violiation before
the programm enters the main routine. In this code I use a shared
library which consist of only one class, here's the header of this
library class:

>>>>>
#include <iostream.h>
#include <TObject.h>
#include <TClonesArray.h>
#include <TLorentzVector.h>
#include <TMath.h>

class TMath;
class TLorentzVector;
class TClonesArray;

const Int_t MAXJET = 10;                // max number of jets
const Int_t MAXTRK = 100;               // max number of tracks

class ZEvent : public TObject {
 public:
  ZEvent();
  ZEvent(TClonesArray* zufoArray,TClonesArray* trackArray,Float_t
*trackChargeArray);
  ~ZEvent();
 
  Float_t GetLtf(Int_t num);
  Int_t GetnTracksInJet(Int_t num);
  Float_t GetChargeOfJet(Int_t num);
  Float_t GetChargeEWOfJet(Int_t num);
  Float_t GetTrackFraction(Int_t num);
  Float_t GetLeadingTrackJetFraction(Int_t num);
  Float_t GetTrackJetFraction(Int_t num);
 
 private:
  TClonesArray jetArray;           // 4vecs of jets
  TClonesArray trkArray;           // 4vecs of tracks
  Float_t *trkChargeArray;         // charge of tracks
 
  ClassDef(ZEvent,0)
};
<<<<<

And here's the output from the debugger:

>>>>>

There are no problems when I use the older root version
3.00, from May 02 2001. 

I hope someone can help me.

Thanks, Chi Nhan.
