During the bootstrap, while Emacs is byte-compiling files, it crashes.
I know that because:

1) I get a message from Windows (not the usual w32_abort dialog)
telling me that Emacs has crashed and asking whether I want to send a
report to Microsoft.
2) Bootstrapping stops until I dismiss that message.

At that point, until I tell Windows to dismiss the report sending, I
have all the time in the world to get the id of the only Emacs running
and attach gdb to it.

3) I know that it is in japanese.el, because it happens while
bytecompiling lisp/language/*, and japanese.el is the only missing
.elc afterwards.

I get the crash in all bootstraps, so if you want me to try something, just ask.
