Description

Hi Bruce,

It seems the latest TrajCluster reconstruction caused segmentation fault in DUNE far detector reconstruction jobs quite often. Here is one example:
lar -c standard_reco_dune10kt_nu_1x2x6.fcl xroot://fndca1.fnal.gov:1094//pnfs/fnal.gov/usr/dune/scratch/users/vito/ci_validation/tracking_efficiency_validation/v07_13_00//sim/prodgenie_nu_dune10kt_1x2x6_detsim_083.root --nskip 46 -n 1

The crash happened on Line 756 of TrajClusterAlg.cxx:
tcc.dbgStp = (tcc.modes[kDebug] && slc.slHits[iht].allHitsIndex == debug.Hit);
where iht = 115043393 but the size of slc.slHits is 4.

When you have a chance, could you please take a look at this?
Thanks,
Tingjun
