There are a few more: In "registers", libraries, files, ... And these makes
a difference when implementing a GC: For example, the "registers", which are
used for temporaries (which may be allocated on the heap, despite the name),
should be registered as root objects to a tracing GC, but (other) free store
objects should not. The fact that one cannot distinguish between these in an
automated manner in C++, makes it very difficult to implement a GC in C++
(other than a reference count).
