I know containers of auto pointers should not be used and can cause problems. What is the actual reason for that? Is there any other kind of “smart” pointer which is safe to use in a container?

Container elements should be truly copyable; auto_ptr’s are not. If you make a copy, the original is modified (it loses ownership). A boost::shared_ptr can be copied, as the two pointers will share ownership afterwards. Thus, it can be used in a STL container.
