Passing TFile* as reference problem

Hi,

I have a problem with ROOT which I have not been able to solve. A minimal code example is attached.

I am passing a TFile pointer f1 to a procedure called files() to load a file. The result of the procedure (the contents of f1) apparently depends on whether files() is called within a loop or directly.

To see the difference, change the line with the comment {1}. You will also need to put a valid path in lines markes with {2}.

Maybe you have an explanation and / or workaround, thanks,
Alexander
