First, you have to add Win2000 in the list of OS !
 Then crash in N03 when shooting an e- of 1 GeV. An e- of 1 MeV is ok.

 I have been able to have the line of the crash through Visual,
it is in CLHEP :

      inline HepInt RandFlat::shootBit() {
        if (staticFirstUnusedBit==0)
          shootBits();
          unsigned long temp= staticFirstUnusedBit&staticRandomInt;
here->    staticFirstUnusedBit>>= 1;
          return temp!=0;
      }

  the calling stack is :

      G4GammaConversion::PostStepDoIt(const G4Track&,const G4Step&)
      G4SteppingManager::InvokePostStepDoItProcs()
      G4SteppingManager::Stepping()
      G4TrackingManager::ProcessOneTrack(G4Track*)
      G4EventManager::ProcessOneEvent()

Could you please try by using one of the latest reference tags, or anyway
install patch01 over release 2.0 ?
Usage of RandFlat::shootBit() has been replaced everywhere in the G4 code
since the public patch and geant4-02-00-ref-02 to allow reproducibility of
events.
