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 B1
{
    void f (char);
    void f (double);
};

struct B2
{
    void f (int);
    void f (double);       // <--- line 10
};

struct D : public B1, public B2
{
    using B1::f;
    using B2::f;
    void g ()
    {
        f ('a');           // should call B1::f(char)
        f (33);            // should call B2::f(int)
    }
};


The compiler gives the following error message:
X.CPP:10: error: `void B2::f(double)' and `void B1::f(double)' cannot be 
   overloaded

I think this is not standard conforming. See 7.3.3/12: "[ Note: two using
declarations may introduce functions with the same name and the same parameter
types. If, for a call to an unqualified function name, function overload
resolution selects the functions introduced by such using declarations, the
function call is illformed. ]"


Kind regards
W. Roehrl
