[Bug c++/20987] New: friend declaration links to two functions


Dear all,

I would like to post a bug 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>
      X.CPP -oX.O


// file X.CPP

struct S
{
    static int f4 ();

    class C
    {
    public:
        C ();
        ~C ();
    private:
        friend int f4 ();

        static int i;
    };
};

int f4 () { return S::C::i; }

int S::f4 () { return C::i; }    // Comeau: member "S::C::i" is inaccessible


The code above compiles fine with GNU. Obviously the compiler binds the friend
declaration in class C to tow functions: to S::f4() and to ::f4() since both
functions can access the private member S::C::i.

It is not clear if the friend declaration should link to S::f4(). There is a
defect report (DR 138) which covers this case.


Kind regards
W. Roehrl
