Dear colleagues,

I am trying to do some simulation on the PndEMC. When I try to access the related MCTrack information of a EmcPoint, there are some problem!

When I use the code:

PndEmcPoint* point = (PndEmcPoint*)fPointArray->At(i);
std::set<FairLink> links = point->GetLinks();

where, "i" is the index of the EmcPoint in the related TCloneArray, "ioman" is the FairRooManager.
The script works fine. However, when I use

point->GetLinksWithType(ioman->GetBranchId("MCTrack"));

The script corrupts. The crash information can be found below. I also attached the full code and the root file.

Any ideas on the crash?

Thank you!

Dong
