Re: fatal error in bootstrap-emacs on Mac OS 10.3.2

[Nozomu Ando]

I think I have found a bug of my code in unexemacosx.c.
I apologize.

On unexmacosx.c:189, the comment of unexec_copy() is not correct.
unexec_copy(dest, src, count) copies too many bytes if count is
not a multiple of 1024.

So unrelocate() (which uses unexec_copy()) may crobber the dumped
emacs.

I think it will be better to correct the body of the function
unexec_copy() to match with its comment.

Please consider the following patch.
(I heard this solved Marc-Antoine's problem, thanks!)

Regards,
Nozomu Ando <address@hidden>
