I think it's because you are giving to the native compiler an already
defined function to compile.

If you use M-x emacs-lisp-native-compile-and-load or (load
(native-compile FILE)) it will work.  I tried the first on 29 and work
around the original issue successfully.

BTW I believe this different handling of the declare could be worth a
separate bug.

Thanks
