Before trying to access:
you need to ensure that the current tracking particle has a creator process object. Primary events (launched from G4ParticleGun or G4GeneralParticleSource) do not have a creator process object since they are primary particles, and thus, when you try to get the process name from your sensitive detector class for primary particles, you create a segmentation fault since there is no creator process in memory to access from the step object.
Test for the creator process, then grab the creator process name. Something like:
G4String CPName; if(aStep->GetTrack()->GetCreatorProcess()!=0) CPName = aStep->GetTrack()->GetCreatorProcess()->GetProcessName();
Hope that helps.
