You can't store a std::auto_ptr<> in stl containers. I think that this is because it has non-const copy semantics.

[bigearsbilly]

you aren't supposed to use them in containers.

an object may be safely pointed to by only one
auto_ptr, so copying an auto_ptr copies the pointer and
transfers ownership to the destination if the source had
already had ownership.

why use pointers? you aren't gaining any space or speed
by using a pointer over a bare int.
the container makes a copy anyway, and copying
a pointer will cost the same.

if you must, use boost::shared_ptr

Better still, use boost::ptr_vector.
