    Yes, they are all cleaned up properly.

    From this link:

    All the elements of the vector are dropped: their destructors are called, and then they are removed from the vector container, leaving the container with a size of 0.

    The [sequence.reqmts] section of the upcoming standard also makes this clear:

    a.clear() destroys all elements in a, invalidates all references, pointers, and iterators referring to the elements of a and may invalidate the past-the-end iterator.
