CCing Stefan who seems TRO for this.

emacs -Q
M-x find-function elisp-mode-syntax-propertize RET
C-U C-M-x

results in the following backtrace:

------------------------- snip -------------------------
Debugger entered--Lisp error: (error "Eager macro-expansion failure: (void-function edeb...")
  error("Eager macro-expansion failure: %S" (void-function edebug-after))
  internal-macroexpand-for-load((setq elisp--eval-defun-result (let ((print-level nil) (print-length nil)) (progn (defalias 'elisp-mode-syntax-propertize #'(lambda (start end) (edebug-enter ... ... ...)))))) t)
  elisp--eval-defun()

  eval-defun((4))
  funcall-interactively(eval-defun (4))
  command-execute(eval-defun)
------------------------- snip -------------------------

Not analyzed any further, but the combination of
`syntax-propertize-rules' and `rx' seems to trigger this error.
