[Bug c++/32676] New: [cxx0x branch] incorrect member address when using delegate constructors and virtual inheritance

[a dot chavasse at gmail dot com]

version: g++0x (GCC) 4.3.0 20070628 (experimental)
(more exactly: branch svn://gcc.gnu.org/svn/gcc/branches/cxx0x-branch, svn
revision 126129)
system type: x86_64-unknown-linux-gnu
configured with: ../gcc0x/configure --program-suffix=0x --disable-multilib
--enable-languages=c,c++


The following code prints two different adresses for m_Count, whereas it should
print the same address twice.
It works properly when not calling the delegate constructor from A's default
constructor.
It also works properly if the "blah" array in B is removed or reduced to a size
of one.

====================================
#include <iostream>

class base
{
        public:
                virtual ~base() {}
                int m_Count;
};

class A : public virtual base
{
        public:
                A( int blah ) {}
                A() : A( 13245 )
                {
                        std::cout << &m_Count << std::endl;
                }
};

class B : public virtual base, public A
{
        public:
                B()
                {
                        std::cout << &m_Count << std::endl;
                }

        private:
                int blah[100];
};

int main()
{
        B* pB = new B;
        return 0;
}
