I have a code segment that is too long to send here but I don’t think the code has an issue. (I think). In my code, I have a method that reruns the main function as many times as I dictate. When I run rerun(1000), it runs the main program 1000 times. However, after like 20-100 reruns, the code stops and I get a *** Break *** segmentation violation. How is it so that my code runs fine after like 20 reruns but then doesn’t work afterward?

That’s impossible to tell without further info. Could you paste the complete output of ROOT?

A first step toward understanding this problem would to compile (possibly via ACliC) your code so that the stack trace shows more information or so that you can use valgrind to pin point the problem.
