I believe you are under the misconception that constructors and
destructors are called by new and delete from the CRT, whereas
in fact they are not - they are inserted by the compiler, while
new/delete merely allocate/deallocate the memory.

Notice Igor carefully referred to global/static objects' constructors/
destructors only, since these are the only ones affected in ATL3.
