I am attempting to “merge”/combine two trees. Both trees have been cloned from other trees. I have attempted hadd:
hadd all.root F1.root F13.root
hadd Target file: all.root
hadd Source file 1: F1.root
hadd Source file 2: F13.root
hadd Target path: all.root:/

And I have made a variety of TTree:MergeTrees attempts:
[code]
TList* list = new TList;
TTree* T1=LoopChain(mparam1);
TTree* T13=LoopChain(mparam13);
list->Add(T1);
list->Add(T13);
list->Print();
cout << list << endl;
TTree* truthtree = TTree::MergeTrees(list);
truthtree->SetName("truth");
[/code]
The result of [code]list->Print()[/code] prints out the two TTrees, as I expect them to. They are not empty, they have all the branches, etc.
The result of the [code]cout << list << endl;[/code] produces a nonempty memory address.
It doesn't crash at [code]TTree::MergeTrees(list)[/code]. Instead (with dbg, because the backtrace by itself doesn't list the problem line) it crashes at [code]truthtree->SetName("truth")[/code]

I don't have trouble merging trees with any of these methods with trees that were not cloned.
To produce the problematic cloned tree, I use, basically:
[code]TChain ch("CCNuPionInc");
ch.Add("somefile.root");
ch.SetBranchStatus("somebranches",1);
ch.SetBranchStatus("otherbranches",0);
TTree* temptruthtree = mch.CloneTree(0);
for(int i=0; i<500; ++i){
ch.GetEntry(i);
temptruthtree->Fill();
}I’ll work on coming up with a simplified piece of code and input files to reproduce the problem. But in the meantime, does anything here look fishy?
