What does this line say in the elisp.info file you have installed:

  Ref: Definition of nth^?264186

What is the number at the end of the line in your case?

And if you type this command:

  M-x find-file-literally RET /path/to/elisp.info RET

then go to this line:

 -- Function: nth n list

and type "C-x =", what does Emacs show in the echo area?

If your elisp.info file is gzip-compressed, then do this instead:

  C-x C-f  /path/to/elisp.info.gz RET
  C-x Function: nth RET
  M-: (position-bytes (point)) RET

and tell what that yields, and how does that compare with the number
at the end of the "Ref:" line shown above.

Thanks.
