No, it is Program_Error in Ada.

Construction /= allocation. Here I repeat the object's life cycle as I see
it:

allocation
   construction (=initialization)
      use (includes assignment and all public operations)
   destruction (=finalization)
deallocation

Well, I think it is possible to roll back an initialization, though it was
not attempted in Ada.
