With the following print-debug patch:

I get the following build log:


[-- Attachment #4: emacs-print.log.gz --]
[-- Type: application/gzip, Size: 30833 bytes --]

[-- Attachment #5: Type: text/plain, Size: 804 bytes --]


I.e. before the first dump the load-path is:

  ("/home/blc/.local/src/emacs/lisp"
   "/home/blc/.local/src/emacs/lisp/emacs-lisp"
   "/home/blc/.local/src/emacs/lisp/progmodes"
   "/home/blc/.local/src/emacs/lisp/language"
   "/home/blc/.local/src/emacs/lisp/international"
   "/home/blc/.local/src/emacs/lisp/textmodes"
   "/home/blc/.local/src/emacs/lisp/vc")

And before the second dump:

  ("/home/blc/.local/src/emacs/lisp")

After the build is done we get:

0. ./src/emacs -Q
1. C-\ TAB
   [No match]
2. C-g
3. M-: input-method-alist RET
   nil
4. M-: (seq-find (apply-partially #'string-search "leim") load-path)
   "/home/blc/.local/src/emacs/lisp/leim"

Here's ~blc/.local/src/emacs/lisp/leim/leim-list.el:


[-- Attachment #6: leim-list.el.gz --]
[-- Type: application/gzip, Size: 6823 bytes --]

[-- Attachment #7: Type: text/plain, Size: 3293 bytes --]

My reading of the log suggests it must be.
