Because shared_ptr captures the destructor at the time it takes
ownership of the object. If this happens when the object is being
created (as in your example) the correct destructor is called even if
it isn't virtual.

It is common for base types that are designed to be managed by
shared_ptr to use protected, non-virtual destructor (watch out for
retarded gcc warnings.)
