Hi,
so I have a class that has an class that has a TClonesArray. I followed the methodolgy used in the examples given in (Event.h/cxx) mentioned in the root document on trees. But when I ran this I get a crash with this stack trace:

Would anyone know what am I doing wrong if the stack trace looks familiar? I tried to step into the debugger but crashes, just when I “step into” the function TTree::Fill(). I would have expected at least to walk down in the above stack track, but for reasons I dont’ understand, it just crashes.
