Fortunately, finally I found the shortest test case 100% reproducible
in 'emacs -Q'.  The line '(set-buffer (get-buffer-create "*test*"))'
is not necessary, it just causes a slightly different error.
Without 'set-buffer', the error is: (args-out-of-range 1737)
With 'set-buffer', the error is: (args-out-of-range 1737 1737)
Just eval in 'emacs -Q':

(let ((message-truncate-lines t))
  (set-buffer (get-buffer-create "*test*"))
