Dear all,

I would like to post a fault report for the GNU C/C++ compiler 3.3-e500.

We use the compiler to generate code for a PowerPC processor.

Used invokation line for the GNU C++ compiler:

ccppc -c -x c++ -ansi -Wall -Werror -mcpu=8540 -fverbose-asm -mbig
      -fmerge-templates -mmultiple -mno-string -mstrict-align -O3
      -fno-exceptions -fno-rtti -fno-builtin-printf
      -I<different include paths>
      -D<differen #define's>
      K.CPP -oK.O



// example program

template <typename> class C1;
template <typename> class C2;

template <typename T_>
class C2<T_*>
{
    typedef T_* T_PAR_TYPE;        <---- k.CPP, line 7
    friend class C1<T_*>;          <---- class C1<int (*)[20]> is a friend
};

template <typename T_>
class C1
{
//public:                          <---- k.CPP, line 14
    typedef typename C2<T_>::T_PAR_TYPE T_PAR;
    struct S1
    {
        T_PAR par;                 <---- k.CPP, line 18
    };

    static void fx (S1&);

public:
    void f (T_PAR ptr);
};


template <typename T_>
void C1<T_>::f (T_PAR ptr_)
{
    S1 s1;                         <---- k.CPP, line 31

    fx (s1);
}



typedef int T_MEM[20];


void f (T_MEM* p1)
{
    C1<T_MEM*> c1;

    c1.f (p1);                     <---- k.CPP, line 45
}



The compiler gives the following error messages:

k.CPP: In instantiation of `C1<int (*)[20]>::S1':
k.CPP:31:   instantiated from `void C1<<anonymous template type parameter> >::f
(typename C2<<anonymous template type parameter> >::T_PAR_TYPE) [with T_ = int 
(*)[20]]'
k.CPP:45:   instantiated from here
k.CPP:7: error: `typedef int (*C2<int (*)[20]>::T_PAR_TYPE)[20]' is private
k.CPP:18: error: within this context


The error messages remain the same if line 14 is un-commented. This seems OK
since the access specification of C1<>::T_PAR should not affect C1<>::S1. The
compiler translates only without complaints if C2<>::T_PAR_TYPE is made public.



With kind regards
W. Roehrl
