Hi everyone,
I have a big problem that I can’t find a solution to.
I have a macro, Run.py, where I run my code on several ntuples.
For most of them I don’t have any type of problem, the code works good and it’s ok.
But for two nutples the code crash and make Segmentation fault (ntuples has only different data but the structure is the same for all of them).
I’ll report the crash:

The code pretty big, so for the moment I avoid to post it. The strange thing is that works for almost every ntuples and not in few ones.
Someone has ideas?
