The Boehm collector cannot move objects around, the D one can.
Oh it can? Really?
Yes. D, for example, requires that objects not be self-referential for
this reason.
I don't think the GC would have problems with fixing up internal
pointers to the object itself. self-referential is prohibited to allow
moving structures by memcpy, e.g. as return value.
Does this mean that you cannot safely implement something as basic as a
circular linked list?
Depends on your implementation, but I would not expect that the nodes of
your linked list could be subject to being moved (mostly happens on the
stack AFAICT), as pointers to the node from other nodes would become
invalid, too.
