I have installed xfitter package using ROOT. Installation was completed successfully
but when I want to run some examples I encounter this error:

 *** Break *** segmentation violation

Hi @MohammadMohammadidoust! Looking at the stack trace, it doesn't look like it's a bug in ROOT because the stack trace shows init_theory_modules () at init_theory.f:13 as the last call, and then something that is optimized out. I think this is rather an xFitter issue.

For these kind of problems with ROOT user code, you can ask in the ROOT forum, but please remember to provide complete instructions and the files necessary to reproduce your issue. See you over there maybe! You can also try to engage with the xFitter community directly.

For now, I will close this issue here because it doesn't look like this is a bug in ROOT. If you are convinced at some point that the problem is really a bug in ROOT, feel free to reopen or to create a new issue!
