Dear Rooters,

I have a strange behaviour with my script. I am trying to read a tree that contains a branch made with my own class (in particular this is a vector<myClass*>). When I try to read the tree from TBrowser or within root prompt, everything is working properly. However when I try to compile exactly the same script (with all the extras needed) it is crashing.

This is the stack trace of the error:

Anyone has experienced something similar?

Thank you for your help,

Dear All,

I found the problem, I report my solution for future memories.
I was not initialising to 0 the vector<myClass*> *myPointer

I was doing:
vector<myClass*> *myPointer;

I should have done:
vector<myClass*> *myPointer=0;

Thank you,
Vito
