This was changed in Emacs 28 a couple months ago:

commit 216c65b135c2b0be7e048cdc6683873b03b99b9a
Author:     Lars Ingebrigtsen <larsi <at> gnus.org>
AuthorDate: Sun Mar 28 19:13:00 2021 +0200

    Use a 64KB page size for pdump
    
    * src/pdumper.c (dump_get_page_size): Use a 64KB page size on all
    architectures, as this many vary between systems (bug#47125).

So I think the problem should be fixed now, but it'd be good to get it
confirmed.
