Re: tree example segfaults

As indicated in the documentation of this example, this tutorial cannot be executed by CINT

//
// to run the example, do:
// .x tree2a.C+ to execute with native compiler
//
//  Note that this example cannot be run under CINT (ie .x tree2a.c)
//  because an interpreted class cannot derive from a compiled class.

You may also have to add the 2 following missing includes #include "TROOT.h"
#include "TMath.h"

These two includes are in version 5.19
