[larsi@stories ~/src/emacs/trunk]$ touch lisp/subr.el
[larsi@stories ~/src/emacs/trunk]$ make; make check-maybe
[...]

1 files contained unexpected results:
  lisp/help-fns-tests.log

This is

1 unexpected results:
   FAILED  help-fns-test-lisp-defun

And indeed:

C-h f last RET

=>

last is a compiled Lisp function in ‘subr.el’.

So updating subr.el leads to Emacs loading the .elc file, not the .eln
file.
