Question Accessing PostStepPoint from ClassifyNewTrack() 

Forum: Event and Track Management
Date: 01 Feb, 2006
From: Sara Vecchio <>

Why, if in the StackingAction I change from

G4ThreeVector position = track->GetPosition();


G4ThreeVector position = track->GetStep()->GetPostStepPoint()->GetPosition();

I get segmentation violation at run time? 
I have read of a similar problem relating to killing the track
but I just want to extract information and I have still not understood
 how to solve it in my case

*** Break *** segmentation violation
 Generating stack trace...
/usr/bin/addr2line: 'DoPET': No such file
 0x0830d442 in G4StackManager::PushOneTrack(G4Track*, G4VTrajectory*) + 0xb2 from DoPET
