Still same error.

This is exactly how I reproduce it:

git clean -xfd
make bootstrap
make check
# 2 files contained unexpected results:
#   lisp/emacs-lisp/eieio-tests/eieio-tests.log
#   lisp/emacs-lisp/eieio-tests/eieio-test-methodinvoke.log
src/emacs -Q

Evaluate this in *scratch*

  (require 'eieio)
  (defclass foo ()
    ((x :initarg :emu
         :initform emu
         :allocation :class
         :accessor get-foo)))
  (get-foo (foo))
  (get-foo 'foo))

I get this backtrace:
