  The entire content of this file is ridden with LEAKS. A bug has been filed,
Shinya Kitaoka 120a6e
  will hopefully
Toshihiro Shimizu 890ddd
  be dealt with ASAP.

  L'intero contenuto del file e' pieno di LEAK. Ho inserito la cosa in Bugilla e
Shinya Kitaoka 120a6e
  non ho potuto
Shinya Kitaoka 120a6e
  fare altro sotto rilascio. Non solo, il codice dei distruttori e' SBAGLIATO -
Shinya Kitaoka 120a6e
  l'ho esplicitamente
Toshihiro Shimizu 890ddd
  disabilitato, tanto non era chiamato cmq.
Toshihiro Shimizu 890ddd
Toshihiro Shimizu 890ddd
  E' da rifare usando SMART POINTERS (boost::scoped_ptr<> o tcg::unique_ptr<>, o
Toshihiro Shimizu 890ddd
  std::unique_ptr<> se facciamo l'upgrade del compilatore).
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
  Da osservare che anche il campo FILE in TPSDReader leaka se viene sganciata
Shinya Kitaoka 120a6e
  un'eccezione...
