--- Comment #6 from Vlad Yaglamunov <vlad at solidsands dot nl> ---
I agree with Richard's explanation. Seems like my first example is an undef=
ined
behavior. In section [basic.stc.dynamic.allocation] par 2, in C++17, was ad=
ded
the following: "Furthermore, for the library allocation functions in
[new.delete.single] and [new.delete.array], p0 shall represent the address =
of a
block of storage disjoint from the storage for any other object accessible =
to
the caller."=
