Ah, indeed, the static heap size is much smaller in the final dump:

Pure-hashed: 24083 strings, 3801 vectors, 38521 conses, 3706 bytecodes, 102 others
Dumping under the name emacs
9663104 of 33554432 static heap bytes used
2777644 pure bytes used
Adding name emacs-25.1.50.1
: paxctl -zex emacs

Also, I get an only slightly larger number when dumping bootstrap-emacs
with the pre-compiled elisp files.  Perhaps, you got the first number
with the *.elc files still being around from a previous test?
