None Segmentation fault with Geant4 10.1

Hi,

if I use Geant4 version 10.1 with my programs using voxelized targets I have a segmentation fault every time I call the following lines in the SteppingAction:


const G4VTouchable* touchable = aStep->GetPreStepPoint()->GetTouchable();
G4int k = touchable->GetReplicaNumber(0);
G4int i = touchable->GetReplicaNumber(2);
G4int j = touchable->GetReplicaNumber(1);


In order to check if the problem was with my code, I copied these lines to the SteppingAction of the Hadrontherapy example and I have also created a SteppingAction in the DICOM example. In both tests I received a segmentation fault, apparently originating from:

G4TouchableHistory::GetReplicaNumber(int) const () from .../geant4/geant4.10.01-install/lib/libG4geometry.so

Interesting enough is the fact that when using these lines in a G4VSensitiveDetector class (e.g. HadrontherapyDetectorSD class in the hadrontherapy example) there is no segmentation fault.


Cheers,
Marco
