sPHENIX tracking discussion

Hi folks,

I reran the macro which kept crashing in jenkins randomly with the 
random seeds I found in the log. It segfaults in the evaluator when 
doing --itr in the tenth event:
#2  SvtxTrackEval::max_truth_particle_by_nclusters(SvtxTrack*) ()
    at 
/home/phnxbld/sPHENIX/gcc-8.3/new/source/coresoftware/simulation/g4simulation/g4eval/SvtxTrackEval.cc:230


226      if(_recoTruthMap != nullptr)
227        {
228          SvtxPHG4ParticleMap::WeightedTruthTrackMap map = 
_recoTruthMap->get(track->get_id());
229          auto itr = map.end();
230          --itr;
231          std::set<int> bestPartSet = itr->second;
232          int bestpart = *bestPartSet.begin();
233          return _truthinfo->GetParticle(bestpart);
234        }


If you want to reproduce this, load these random seeds in the default 
macro right after the PHRandomSeed::Verbosity(1);

  PHRandomSeed::Verbosity(1);
  PHRandomSeed::LoadSeed(3774315877);
  PHRandomSeed::LoadSeed(2499985291);
  PHRandomSeed::LoadSeed(2932553874);
  PHRandomSeed::LoadSeed(2819539040);
  PHRandomSeed::LoadSeed(3300000437);
  PHRandomSeed::LoadSeed(2299457957);
  PHRandomSeed::LoadSeed(1174569578);
  PHRandomSeed::LoadSeed(3107449026);
  PHRandomSeed::LoadSeed(3665107792);
  PHRandomSeed::LoadSeed(458807823);
  PHRandomSeed::LoadSeed(3195705626);
  PHRandomSeed::LoadSeed(3638009118);
  PHRandomSeed::LoadSeed(4287452851);
  PHRandomSeed::LoadSeed(2124280620);
  PHRandomSeed::LoadSeed(4020470360);
