Warning possible bug in G4HCofThisEvent

I may have found a pointer-related bug in G4HCofThisEvent.

GetHC(G4int i) is supposed to return a NULL when the collection ID does not exist.

Here is the code (from UserEventAction):

  G4VHitsCollection *vHC = 0;
  vHC = HCE->GetHC(collID);

  // doesn't work when HC does not exist!
  if(!vHC || vHC == NULL || vHC == 0)
    G4cerr << "HC not found" << G4endl;

I am getting "0x9" as my pointer value for vHC instead of "0x0".

This means that I'm having a hard time checking whether or not a hits collection actually exists as GetHC is not correctly giving back a NULL when it doesn't.
