To work around ambiguities in the case of multiple-inheritance
interface types (which inherit XInterface
more than once),
dervied Reference
instances use
reinterpret_cast
to switch _pInterface
from a
pointer to XInterface
to a pointer to a derived interface
type, and vice versa. In principle, this is not guaranteed to
work. In practice, it seems to work on all supported
platforms.
