Bug description
I'm not completely sure this is a bug, but I suspect it is.
$ cat a.ml
let () = Printf.printf "a is loaded\n%!"
$ cat b.ml
include (Pack : sig end)
$ ocamlopt -c -for-pack Pack a.ml
$ ocamlopt -pack a.cmx -o pack.cmx
$ ocamlopt -a pack.cmx -o pack.cmxa
$ ocamlopt -c b.ml
$ ocamlopt pack.cmxa b.cmx
$ ./a.out
When run on 4.01, the printf statement executes.
With 4.02, it does not.

Interesting.
It doesn't seem to be related to module aliases, but may be the consequence of some extra simplifications on lambda-code involving modules.
I'm still confused at why your b.ml and the following c.ml end up being compiled differently:
include (A : sig end)
Just reverting a StrictOpt to Strict solved the problem, with
no other side-effects (since there is a coercion, this is not
a module alias).
Actually this is not related to pack: you could obtain
the same result by coercing a non-empty signature to
an empty one:
$ cat a.ml
let () = Printf.printf "a is loaded\n%!"
let x = 3
$ cat c.ml
include (A : sig end)
$ ocamlopt -c a.ml
$ ocamlopt -c c.ml
$ ocamlopt c.cmx -o c.opt # !!!
