User-agent: Wanderlust/2.15.9 (Almost Unreal) SEMI-EPG/1.14.7 (Harue) FLIM/1.14.9 (Gojō) APEL/10.8 EasyPG/1.0.0 Emacs/27.0 (x86_64-pc-linux-gnu) MULE/6.0 (HANACHIRUSATO)

Start Emacs with "emacs -Q" and run following code

(require 'cl-lib)
(cl-defstruct (stt (:noinline t))
  slt-a slt-b)

(let ((inst (make-stt :slt-a 1 :slt-b 2)))
  (setf (stt-slt-a inst) 2))

Will get error "Symbol’s function definition is void: \(setf\ stt-slt-a\)"

It seems that the accessors of struct defined with :noinline can't be expand
with "setf" directly.

This issue probably introduced at commit 
144b2243b7cee4adbc3217d871c575921f95af54.
