Implementing SmartPtr - compiler bug?

[ketmar via Digitalmars-d-learn]

just checked this with gdc and dmd head. interesting that

  a = a.init;

works the same in gdc and in dmd: just calls destructors for structs.
but doing

  a[] = S.init

works different. gdc does the same as in the first case: just calling
destructors for all array elements. but dmd head calls postblits
before destructing for all array elements (and then calls destructors
for this copied elements). i.e.

first case:

  destructor: bff51e2b
  destructor: bff51e2a
  destructor: bff51e29
  destructor: bff51e28

second case:

  postblit: bff9405c
  destructor: bff94028
  postblit: bff9405d
  destructor: bff94028
  postblit: bff9405e
  destructor: bff94028
  postblit: bff9405f
  destructor: bff94028
  destructor: bff9405f
  destructor: bff9405e
  destructor: bff9405d
  destructor: bff9405c

besides, dmd calls destructor for the first array element four times
(bff94028).

i think that this is definitely compiler bug. if dmd insists on
postbliting, it should at least call destructors for all array
elements, not only for the first one four times. ;-)
