If at all possible, could you find out where does this EOVERFLOW come
from (it could also be a garbage value of errno, but the failure to
load is real)?  The error message comes from lread.c:1144, but the
question is: why does the load fail?  Perhaps you could step through
the relevant code, like this:

  gdb ./temacs.exe
  (gdb) break Fload
  (gdb) run -batch -l loadup dump

Then, when the breakpoint in Fload breaks, step through the code,
stepping into the 'openp' function, and see why the latter fails to
open the loadup.el file.

(I don't think you need to rebuild Emacs for this, since temacs.exe
should already exist on that system.)

Thanks for testing the pretest version.
