>Description:

Here is the source:
--cut
class Info
{
    friend class Creator;
    Info();
    struct InfoRep;
    InfoRep *_rep;
};

struct Info::InfoRep
{
    char _data[16];
};

Info::Info()
    :_rep(new InfoRep) {}

class Outer
{
    friend class Creator;
    Outer(Info *info);
    struct OuterRep;
    OuterRep *_rep;
};

struct Outer::OuterRep
{
    Info* _info;
    OuterRep(Info *info);
};
Outer::OuterRep::OuterRep(Info *info)
    :_info(info) {}

Outer::Outer(Info *info)
    :_rep(new OuterRep(info)) {}


class Creator
{
public:
    Creator();
};
Creator::Creator()
{
    Info info;
    Outer outer(&info);
}
int main(int argc, char *argv[])
{
    Creator c;
}
--cut
Here is the compiler outputd@rabid:/home/rabid> g++ test.cc 
test.cc:10: `struct Info::InfoRep' is private
test.cc:22: within this context
rabid@rabid:/home/rabid> 
>How-To-Repeat:
	compile it.
>Fix:
    If I move line 'friend class Creator;' in class Outer after the declaration
    of struct OuterRep everything compiles OK:
--cut
class Outer
{
    Outer(Info *info);
    struct OuterRep;
    OuterRep *_rep;
    friend class Creator;
};
--cut
