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.
