[Bug c++/24173] [4.0/4.1/4.2 regression] ICE with garbage collection

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #6 from pinskia at gcc dot gnu dot org  2005-11-29 23:08 -------
Shorter testcase:
template <typename T> struct F;
template <typename T> F<T> &operator<<(F<T>&, const char*);
template<typename T>
struct F
{
  friend F& operator<< <>(F&, const char*);
};
typedef F<char> F1;
template<typename> struct X;
typedef X<int> X2;
F1& operator<< (F1&, const X2&);
template<typename> struct X
{
  static void foo();
  friend F1& operator<< (F1&, const X2&);
};
template<typename T>void X<T>::foo()
{
  F1 g;
  g <<"";
}
-----
Commenting out the following ggc_free:
  /* The NEWDECL will no longer be needed.  Because every out-of-class
     declaration of a member results in a call to duplicate_decls,
     freeing these nodes represents in a significant savings.  */
  ggc_free (newdecl);

makes the testcase to work.
