#include <iostream>

int main()
{
    struct pod {
        int i;
    };

    struct inherit : pod {
        inherit() : pod() {}
    };

    struct compose {
        compose() : p() {}
        pod p;
    };

    inherit i;
    compose c;

    std::cout << i.i << std::endl;
    std::cout << c.p.i << std::endl;
}

In both cases the pod object is explicitly value-initialized, which according
to 8.5para5 means that "every non-static data member ... is value-initialized"

compose::pod::i is value-initialised, inherit::i is not.  This can be seen from
the values printed out for i.i and by using Purify.

Same result with GCC 4.1.1, 3.4.3, 3.3.4 on Solaris 9, GCC 3.4.3 on AIX 5/3

Valgrind is being weird so I can't test it on Linux, butI don't think it's
platform-dependent.
