Hi Chris and Joe

Oh, interesting. I actually bumped into the same problem in 
https://github.com/sPHENIX-Collaboration/coresoftware/pull/1490 
And implemented a fix at this line:
https://github.com/sPHENIX-Collaboration/coresoftware/pull/1490/files#diff-f579f493152e70c2fcdf5cff4f2485d55dc1cca3db78dff19ba17bfd05870182R229

I still have trouble to validate this PR with the MDC2 Run4 data and adding 
small changes. But if it pass Jenkins for the default macro, welcome to merge 
it. 

Cheers

Jin

Subject: [Sphenix-tracking-l] jenkins crashes

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);
