Basically, it should work in Geant4.

I suppose you used N03 example and did it at SteppingAction.
If so, you have to take care of the structure of physical volume.
Because  "World volume", does not have a mother volume,
the return value from touchable might be NULL.

  Please try, for example,

  G4VPhysicalVolume* volume1
  = aStep->GetPreStepPoint()->GetTouchableHandle()->GetVolume(1);

  G4String mname="No more";
  if ( volume1 ){
    mname = volume1->GetName();
  G4cout << " v1 : " << mname <<G4endl;
