Hi Yasuhiro,
Thanks for reporting this problem (not specific to the new version
2.00/13).
A protection was missing in the TDirectory destructor automatically
called by the TROOT destructor at the end of your Root session.
The problem happens when a TF1 object is created and no Root files are
connected.
