Fault report

[Wolfgang.Roehrl@de.gi-de.com]

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
-mmultiple
      -mno-string -mstrict-align -O3 -fno-exceptions -fno-rtti
      -I<different include paths>
      -D<differen #define's>
      Y.CPP -oY.O



// example program

#define MODE 1         // 0 or 1


template <typename T_>
struct type_tag
{
    typedef T_ type;
};



template <typename T_>
struct XYZ
{
    XYZ ()
    {
        ptr1 = new T_;
        ptr2 = 0;
    }

    template <typename U_>
    XYZ (const type_tag<U_>&)
    {
        ptr1 = 0;
        ptr2 = new U_;
    }

    template <typename U_, typename P_>
    XYZ (const type_tag<U_>&, const P_& p)
    {
        ptr1 = 0;
        ptr2 = new U_(p);
    }

private:
    T_* ptr1;
    void* ptr2;
};


XYZ<int> xyz1;

type_tag<char> t;
XYZ<int> xyz2 (t);
XYZ<int> xyz3 (t, 'a');

typedef type_tag<char> TT;

XYZ<int> xyz4 (TT());                       // <--- object is not allocated
XYZ<int> xyz5 (type_tag<char>());           // <--- object is not allocated

#if (MODE == 1)
  XYZ<int> xyz6 (TT(), 'a');                // <--- 'syntax error' (line
53)
  XYZ<int> xyz7 (type_tag<char>(), 'a');    // <--- 'syntax error' (line
54)
#endif


If the macro MODE is defined to 1, the compiler gives the following error
messages:

y.CPP:53: error: type specifier omitted for parameter
y.CPP:53: error: syntax error before 'a'
y.CPP:54: error: type specifier omitted for parameter
y.CPP:54: error: syntax error before 'a'


If MODE is defined to 0, I get no error message but the objects xyz4 and
xyz5
are neither allocated nor constructed. (The corresponding assembler listing
is
attached as file GNU2.TXT.)



With kind regards
W. Roehrl
