I confirm the build it's broken on my 32bit env as well, (but not on the
64 one).

Loading the second dump, while we are relocating the ediff-hook
compilation unit, we realize (@ pdumper.c:5304) that its file field is
not a cons as expected but just a string.

Now the question is why this is not fixed-up in loadup.el:477 as for the
other compilation units?
