Received the following error:
bytecomp-bug.el:9:4:Error: Args out of range: 312, 0, 255

When byte-compiling a file with the following elisp:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

(defmacro many-forms ()
  (let ((body '()))
    (dotimes (i 20000)
      (setq body (cons '(message "more") body)))
    `(progn ,@body)))

(if (eq 1 a)
    (many-forms)
  (message "else"))

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Suspect a byte overflow at line 856 in bytecomp.el
The argument of a goto is bigger than 16 bits.
