Hi Jarek, formally what you do is not correct C++. f is first defined as a pointer to a TFile and then in the same scope it is redefined as a TFile. However, I agree that a crash is not really friendly, especially for an interactive environment. Masaharu what is your opinion? Maybe you could protect this? Anyway, to clean the global scope use gROOT->Reset() just after the delete f and it will work. Cheers, Fons.
