#include        <iostream>

struct  B1
{
        B1(int i):i_(i) {       }
        int i_;
};

struct  B2
{
        B2      (void)  {       }
};

struct  Initializer
{
        B1      b1(void)        const   {       return  B1(1);  }
        B2      b2(void)        const   {       return  B2();           }
};

struct  D       :       public  B1,     public  B2
{
        D       (       const Initializer       &init   )       :      
B1(init.b1()),  B2(init.b2())   {       }
};

int     main    (void)
{
        d(Initializer());

//      The line above produces the following error in g++ 3.4.4 under cygwin:

//      bug.cpp: In function `int main()':
//      bug.cpp:35: error: request for member `i_' in `d', which is of
non-class type `D
//      ()(Initializer (*)())'

//      Commenting out that line and uncommenting the following two lines:

//              Initializer     init;
//              D       d(init);

//      compiles without error in g++ 3.4.4 under cygwin, but produces the
output:
//      i_=0

//      Under MS Visual C++ 6.0 either one compiles without error and produces:
//      i_=1
//      which appears to be correct.

        std::cout       <<      "i_="   <<      d.i_    <<      std::endl;

        return  0;
}
