      Description

      I've encountered a ROOT file that I can read just fine using `TTree::Scan`, `TTree::Draw` and similar, but I can't use `TChain` - this results in a segfault, which is a showstopper for using `RDataFrame`.

      Reproduce with

      c = ROOT.TChain("CollectionTree")                                                                                                                                             
      c.Add("/eos/user/c/cburgard/dbg/test.root")                                                                                                                                   
      c.LoadTree(0)
