As in, if you load emacs-lisp/eieio-core in site-load.el with dump-mode
pdump without having byte-compiled eieio-core first, the load
cedet/semantic/loaddefs.el, you will get a cryptic error message stating
stringp: 0 is not a string.  And upon investigation, the closure for
def-eieio-autoload mysteriously has a "(format 0 cname)" in the code, even
though it's not 0 in the eieio-core source code.
