Subject: bug#55355: TBD: inappropriate inlining, cmacro errors

Hi all! I encountered inlining errors, unfortunately I have no idea what
is causing them.

Here is the code:

(cl-defstruct (foo (:constructor foo<-list ((bar _ baz))))
  bar
  baz)

(foo<-list '(1 2 3))                    ; does not work

(funcall #'foo<-list '(1 2 3))          ; does not work

(apply #'foo<-list '(1 2 3) nil)        ; does work

Here is the backtrace:

Debugger entered--Lisp error: (wrong-number-of-arguments foo<-list--cmacro 2)
  signal(wrong-number-of-arguments (foo<-list--cmacro 2))
  (if (= (length --cl-rest--) 3) (pop --cl-rest--) (signal 'wrong-number-of-arguments (list 'foo<-list--cmacro (length --cl-rest--))))
  (let* ((--cl-rest-- (if (= (length --cl-rest--) 1) (car --cl-rest--) (signal 'wrong-number-of-arguments (list 'foo<-list--cmacro (length --cl-rest--))))) (bar (if (= (length --cl-rest--) 3) (pop --cl-rest--) (signal 'wrong-number-of-arguments (list 'foo<-list--cmacro (length --cl-rest--))))) (_ (pop --cl-rest--)) (baz (car --cl-rest--))) (cl-block foo<-list--cmacro (cl--defsubst-expand '(bar _ baz) '(cl-block foo<-list (record 'foo bar baz)) nil nil nil bar _ baz)))
  foo<-list--cmacro((foo<-list '(1 2 3)) '(1 2 3))
  apply(foo<-list--cmacro (foo<-list '(1 2 3)) '(1 2 3))
