A more thorough use of Google brought me the this:

Quote:
Whenever a temporary object is created for the sole purpose of being copied and subsequently destroyed, the compiler is allowed to remove the temporary object entirely and construct the result directly in the recipient (i.e. directly in the object that is supposed to receive the copy).

This process is called elision of copy operation. It is described in [class.copy.elison] in the language standard.

In this case

B* bptr = new B(B(aobj));
can be transformed into

B* bptr = new B(aboj);

even if the copy constructor has side-effects.
Mircea
