[Bug c++/13262] New: "xxx is private within this context" when initializing a *self-contained* template class

[fmonica at ce dot unipr dot it]

This code will compile successful with gcc <= 3.2.3 but doesn't work with gcc 
3.3.1 or 3.3.2: 
----------------------------------------------------- 
template < typename T > 
class Aclass 
  { 
  private: 
    Aclass() {} 
    static Aclass instance; 
  }; 
 
template < typename T > Aclass<T> Aclass<T>::instance; 
 
 
template class Aclass<int>; 
----------------------------------------------------- 
 
The gcc compiler emits an error like this: 
test.cc: In instantiation of `Aclass<int> Aclass<int>::instance': 
test.cc:12:   instantiated from here 
test.cc:5: error: `Aclass<T>::Aclass() [with T = int]' is private 
test.cc:9: error: within this context 
 
This code also works if an explicit instantiation of "instance" is added 
before the last line: 
Aclass<int> Aclass<int>::instance; 
 
That strategy (self contained class with private ctor) will be useful to build 
pattern like "Singleton", proposed by GoF. Of course there are some other ways 
to do this :-) 
 
I'm in doublt, but I think the code should be correct...

Confirmed. Kriang, you are the friendship expert: I am not quite sure
what the standard says, but the present behavior doesn't really
make much sense. What do you think?

I should say that date that I just referenced is for the mainline being broken again (it was fixed at 
one point between the time 3.3 branched and that date: Search converges between 2003-02-25-
trunk (#231) and 2003-02-26-trunk (#232).).

It also was broken before the branch: Search converges between 2002-10-11-trunk (#101) and 
2002-10-12-trunk (#102).

It was never fixed on the 3.3 branch though.

Yup, this should compile.  Somewhere in deferred access checking code is broken.
