Fixed in changeset 83:22cbbe87385b:

The problem is that under 64-bit G++ 3.4.5, sizeof(unsigned int) is 4
while sizeof(void*) is 8.  So rose::gc::registry::address_type is not
long enough to hold a pointer.

The solution is:

    typedef
        boost::uint_t<sizeof(void*) * 8>::exact
        address_type;
