I was able to cut this down to a single expression that causes the core dump:
=====> icomplete-test.el <==============
(defvar icomplete-overlay (make-overlay (point-min) (point-min) nil t t)
  "Overlay used to display the list of completions.")
===============================
 time emacs -Q -batch --eval '(load "icomplete-test")' --eval
'(dump-emacs-portable "test.pdmp")'
Loading icomplete-test.el (source)...
