I compiled Emacs as a 32-bit executable.

If I run only temacs.exe without any arguments, I get a very quick
> backtrace:


I also traced the execution of `temacs -batch -l loadup dump' with windbg,
and got a similar stack trace as Fabrice (I breakpointed Fgarbage_collect):

When I stepped out Fgarbage_collect, the error occurred just after this gc
at here in eval_sub:

if (!CONSP (fun))
xsignal1 (Qinvalid_function, original_fun);

I also tried removing most of loadup.el, and temacs can execute only the
first few lines, and even an additional `(+ 1 1)' caused temacs to exit
with the "DEAD" message. As I previously reported, I guess that the first
garbage collection cycle does not mark any read-in form, thus all of them
are collected (and their car set to Vdead).
