Patrice,
Apologies!
deleting the chain does not delete the current file and the Tree.
In the TChain destructor, the current file is not deleted.
I have fixed the problem in the development version.
Meanwhile, you can solve this memory leak problem. Instead
of deleting the chain, do:
delete chain->GetFile();

Thanks for reporting this problem.
