>Description:
This is a regression on 3.4:
------------------------
template <typename> class X {
  private:
    struct Inner;

    template <typename R>
    friend typename X<R>::Inner * foo () { return 0; };
};
template class X<void>;

struct U {
    void bar () { foo<void> (); };
};
-------------------------

g/a> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c bug33-1.cc
bug33-1.cc: In function `typename X<R>::Inner* foo()':
bug33-1.cc:6: internal compiler error: in is_specialization_of, at cp/pt.c:860
Please submit a full bug report,

The code does compile with 3.2.2, so this is a regression.
Presently, the code does not compile with 3.3, but that is
a separate matter: Kriang has fixed this on the mainline,
but apparently the fix has not been backported to 3.3, 
although the patch that caused this has been applied to 3.3.
I'll contact him separately about this.
