Hi gurus,

Under VC7.1/8,

    struct xxx : std::vector<int>
    {
        virtual void foo() = 0;
    };

    void test(xxx& rng)
    {
        BOOST_FOREACH (int x, rng) {
        }
    }

makes error,

    foreach.hpp(361) : error C2259: 'xxx' : cannot instantiate abstract class

GCC3.4.4 compiles.
Is this wrong code?
