Memory leak with circular TTree

See the forum post at http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=18343&p=78077&hilit=bloer#p78077 . With a circular TTree repeatedly calling Draw with a single entry, I quickly run out of memory.

I believe that this is due to the TMethodCall created at line 3295 of TTreeFormula.cxx http://root.cern.ch/root/html534/src/TTreeFormula.cxx.html#xlSICB not being deleted if the method is found. I suggest replacing creation by the new operator with a simple object.
