Hello,

TTree::CopyTree() crashes when it sees an end of an ntuple in a TChain of
multiple ntuples.
If I try something like this:

[]  .L myclass.C
[]  myclass mmm
[]  TTree* small = mmm.fChain->CopyTree("cal[0]>80")

 *** Break *** segmentation violation

'myclass' was generated with MakeClass(), from TChain of multiple
ntuple files.

I am working on the version 3.05/00.

Best,
