TrajCluster

There are several places in Utils.cxx that use std::nearbyint. Here is one example around line 3410:

      // next make TPs on the wires that don't have real TPs
      TrajPoint ltp;
      // put ltp at the vertex position with direction towards the end point
      MakeBareTrajPoint(vx2.Pos, tj.Pts[tj.EndPt[end]].Pos, ltp);
      if(ltp.Dir[0] == 0) continue;
      unsigned int wire = std::nearbyint(ltp.Pos[0]);
      ltp.Chg = 0;
      unsigned short indx = wire - loWire;
      // Break if we found a real TP
      if(tjpt[indx].Chg == 0) tjpt[indx] = ltp;

In one event, ltp.Pos[0] is negative (-0.642913) and wire was assigned the maximal unsigned integer value 4294967295.

We need to review the code and protect against the case where Pos is negative.
