Re: c++/9377: g++ 64bit calls wrong function -> Multi-inheritance: pointerto member function of the 2nd base calss points to wrong place

[axiong at ca dot ibm dot com]

Actually, with the C++ compiler (xlC) on AIX, for both 32-bit and 64-bit
compiling,  we can do:
   PMF aPMF = (char *(D::*)()) &B2::bar ;
And also,  with g++ for 32-bit compiling, we can do:
   PMF aPMF = (char *(D::*)()) &B2::bar ;

The problem is only for g++ 64-bit compiling: we can not do it only for g++
64-bit compiling.
I believe that the code is correct accorging to standard C++. Please take a
look.

Regards,

Andrew

State-Changed-Why:
    You can't do this:
      PMF aPMF = (char *(D::*)()) &B2::bar ;
    If you want to call B2::bar with a pointer to a D object,
    then you will have to take its address as
      &D::bar
