9293	multi_index_container iterator needs base object size	anonymous	Joaquín M López Muñoz	"The reason this is a bug is because I cannot define 2 classes A&B that will be stored in sequenced containers, and have A&B each hold an iterator to the other's container.

For example, this works:
{{{
struct A;
struct B {
  std::list<A>::iterator a_it;
};
struct A {
  std::list<B>::iterator b_it;
};
}}}

However, if I want to replace both lists with sequenced multi_index_containers, I can no longer compile it.

The problem is that the iterator to a multi_index_container somehow calls sizeof on the stored class, so the forward declaration is not enough to compile."	Bugs	closed	To Be Determined	multi_index	Boost 1.46.0	Problem	wontfix	multi_index_set
