This sounds somewhat like the method in Laine Stump's article in
_EXE_, vol. 7, Issue 10 on April 1993. The article's title is:
"Garbage Collection in C++". Could you get a copy of this and see how
it compares? For example, Laine uses a class, tGCPtr, where "Each
tGCPtr has a second tGCObject* which points to the object containing
this tGCPtr (its 'parent') or contains 0 if the tGCPtr is global or
auto". This 2nd member sounds like your placed_ptr_header ::m_owner.
