      Description

      RooAbsPdf is not existing outside its range used previously with fitTo.

      The consequence is that those that use it in a background modelization/spurious signal study will have completely wrong results if they not realize it. The solution for the moment is to recreate* a pdf with the numerical parameters values of the previous pdf.

      See attached a minimum reproducible example, and also some slides that describe the problem (only the last page describes the problem while the previous ones describe the environement)
