Example:

boost::container::list<std::pair<int, int>> list;
.../boost/container/allocator_traits.hpp:403:11: error: invalid use of incomplete type 'struct boost::container::dtl::pair<int, int>'
  403 |    {  p->~T(); (void)p;  }
      |       ~~~~^

.../boost/container/detail/is_pair.hpp:59:8: note: declaration of 'struct boost::container::dtl::pair<int, int>'
   59 | struct pair;
      |        ^~~~

Thanks for the patch. I'm applying and alternative patch as more containers (like slist) are affected by the same bug.
