In everyday use there is no real difference. "free store" is a term
with a specific meaning used in the C++ language standard. "heap" is
a common usage term to refer to the free store, but "heap" is not used
in the C++ language standard.

Nothing. They both refer to Level 3 or System Memory.

In the context of C++, they are the same.

According to another recent thread on the same issue it would appear
to be nothing (i.e. the terms are interchangeable).
OTOH if a specific C++ environment's new/delete do not use the same
memory pool as malloc/free you might find it useful to use one of
these terms to name the new/delete memory pool and the other to name
the malloc/free memory pool (of course it won't guarantee that anyone
else you communicate with will be sure which one you are referring to
:).

No, those are not answers, they are just Herb's opinions. In the context
of his own writing that terminology is fine but it carries no weight
anywhere else.

I'm no expert, but the way I see it is:
* allocations from the heap are destroyed using free()
* allocations from the free store (via operator new) are destroyed
using operator delete
Doesn't this lead to quite a concrete distinction if 'new' and
'delete' are overridden?

Could you please explain what you mean by this. All memory is managed
by the system, at least on the systems I know. And where any
particular piece of memory is at any given moment (cache, main memory,
paged to disk, etc.) will depend on the system, and will change in
time.
