There's no data structure description, but there is mention of a
static "reference containing map" on p. 267 (chapter 10) of
Jones/Lins. That paragraph mentions [Detlefs,1992]:

The Detlef reference maps are per class and don't describe a map for
the stack or static area. Nor do the maps handle pointers to vectors,
AFAICT. There was a working example of such a map that handled vectors
or any kind of stl like container; however, it's no longer being
developed:
