In addition to that, it's also possible that the objects that these
pointers point to should not be managed by this container, in which
case, use of std::deque or std::vector without explicit deleting is just
fine.  Double-checking the code where it's used seems to suggest that
that may be the case, but again I'm not a Writer guy so don't take my
word for it. ;-)

One thing that you might try is (if the above is true) to store const
pointer instead of a plain pointer to see if that compiles, and if it
does, then you can remove those const_cast that you added when inserting
pointers to the new container.
