Hello!
Configuration with a modified configure script (see bug#9755) and compilation are fine, until it's time to create emacs from temacs:
--- Load Commands written to Output File ---
Writing segment __PAGEZERO @ 0 ( 0/ 0x1000 @ 0)
Writing segment __TEXT @ 0 (0x1b2000/0x1b2000 @ 0x1000)
Writing segment __DATA @ 0x1b2000 (0x1dc000/0x1dc000 @ 0x1b3000)
section __dyld at 0x1b2000 - 0x1b201c (sz: 0x1c)
section __nl_symbol_ptr at 0x1b201c - 0x1b2b08 (sz: 0xaec)
section __la_symbol_ptr at 0x1b2b08 - 0x1b36d0 (sz: 0xbc8)
section __const at 0x1b36d0 - 0x1b4b08 (sz: 0x1438)
section __data at 0x1b4b10 - 0x349c92 (sz: 0x195182)
unexec: unrecognized section name in __DATA segment
Before it was reported:
2 LC_SEGMENT 736 __DATA 0x1b3000 0x1dc000
__dyld 0x1b3000 0x1c
__nl_symbol_ptr 0x1b301c 0xaec
__la_symbol_ptr 0x1b3b08 0xbc8
__const 0x1b46d0 0x1438
__data 0x1b5b10 0x195182
__static_data 0x34ac92 0x3
__pu_bss2 0x34ac98 0x5418
__pu_bss4 0x3500b0 0x8634
__bss2 0x3586e4 0x2faec
__bss4 0x3881d0 0x6564
So it's presumingly the unconventional __static_data section name that produces the premature end of dumping. The GCC 4.6.1 I am using is not supported and not modified by Apple – is updating unexmacosx.c worth the effort?

This problem still exists. The Apple modified compilers GCC 4.0, GCC 4.2, and LLVM GCC 4.2 plus the unmodified compilers GCC 4.4.6 and GCC 4.5.3 all can build GNU Emacs 24.1.50, but unmodified GCC 4.6.3 still fails on PPC Leopard, Mac OS X 10.5.8.
It is similar to the situation on intel Snow Leopard, Mac OS X 10.6.8: GCC 4.6.3 cannot produce bootstrap-emacs. Here is a try for 32-bit executable and --with-wide-int:

We obviously know how to deal with all of the preceding sections...

While unexmacosx.c doesn't yet know how to deal with
__DATA.__static_data, it would be easy enough to add it: just dump
from memory, like __DATA.__data. (Apple's own assembler even has a
".static_data" shorthand for switching this section, they just never
got around to making the compiler actually use it.) The real trouble
is with these sections:

You see, recent versions of GCC generate more-or-less arbitrarily many
BSS sections on Darwin (see the darwin_output_aligned_bss () function
in gcc/config/darwin.c). This is a problem for us because of what we
try to do with BSS sections:
else if (strncmp (sectp->sectname, SECT_BSS, 16) == 0)
{
extern char *my_endbss_static;
unsigned long my_size;
sectp->flags = S_REGULAR;
/* Clear uninitialized local variables in statically linked
libraries. In particular, function pointers stored by
libSystemStub.a, which is introduced in Mac OS X 10.4 for
binary compatibility with respect to long double, are
cleared so that they will be reinitialized when the
dumped binary is executed on other versions of OS. */
my_size = (unsigned long)my_endbss_static - sectp->addr;
if (!(sectp->addr <= (unsigned long)my_endbss_static
&& my_size <= sectp->size))
unexec_error ("my_endbss_static is not in section %.16s",
sectp->sectname);
if (!unexec_write (sectp->offset, (void *) sectp->addr,
my_size))
unexec_error ("cannot write section %.16s", sectp-
>sectname);
if (!unexec_write_zero (sectp->offset + my_size,
sectp->size - my_size))
unexec_error ("cannot write section %.16s", sectp-
>sectname);
if (!unexec_write (header_offset, sectp, sizeof (struct
section)))
unexec_error ("cannot write section %.16s's header",
sectp->sectname);
}
To do this for these new BSS sections, we'd need to insert dummy
markers into each of these sections. This would be manageable enough
if it were only these four, but it isn't necessarily: there are two
categories we care about (__bss, used for statics, and __pu_bss, used
for globals; the other two are for zero-length objects), and these
each get one section per object alignment.
For example, take a gander at this:
iMac:ppc user$ otool -arch ppc -l /sw/src/fink.build/gcc47-4.7.1-1000/
darwin_objdir/gcc/cc1plus | grep bss
sectname __bss2
sectname __pu_bss2
sectname __bss3
sectname __pu_bss0
sectname __pu_bss3
sectname __bss1
sectname __bss12
sectname __bss0
Now, we could *still* add a bunch of dummy variables to deal with all
alignments within some range, but this might end up wasting a lot of
space for the higher alignments (in theory, I think it could be kept
down to 4x the highest alignment), and would be quite ugly in any
case. (Also, the numbers appear to be log2(alignment) in GCC 4.7 but
just aligment in GCC 4.6.) Unfortunately, it seems that Apple's tools
don't like zero-length sections/objects, so we can't use those for the
markers (and for which reason they get their own sections). How zero-
length objects (which on other platforms are allowed to share
addresses with other objects) could be of any use in their own
sections is beyond me...
I suppose, though, that if we could be sure that we aren't linking in
any static libraries with these *new* BSS sections which will have
trouble because of Emacs' dumping them, we could just skip that part;
then all we'd need to do is make sure that my_endbss_static refers to
an address in __DATA.__bss, not __DATA.__bss1 or __DATA.bss2 like it
would naturally end up at on GCC 4.6 or 4.7 (respectively). (And make
unexmacosx.c dump these new BSS sections, of course.)

Apple itself states in http://developer.apple.com/library/mac/#qa/qa1118/_index.html that they "do not support statically linked binaries on Mac OS X." And from my experience it's really a bit complicated to build them. So your approach should be OK and work in the average case. And those few, if at all, who try to build static Emacsen on Mac OS X might need something else...

Well, after my GCC 4.7 build finished, I had a go at building Emacs with
it and (after getting distracted for a bit playing with the
--enable-gcc-warnings flag) I got temacs to build and link. (There was
some awkwardness involving the -fobjc-exceptions flag that we'll need to
straighten out...)
I decided I might as well try the simplest thing that could possibly
work: just dump __DATA.__static_data in the usual way, and dump these
new BSS sections like __DATA.__bss, only in their entirety rather than
messing about with markers.
When my first try ended in SIGSEGV, I ran "gobjdump --all" on temacs and
didn't see any evidence of staticly-linked libraries besides libgcc and
gnulib; then I noticed that I hadn't looked closely enough at the code
I'd copied and pasted into my new "else if" clause and rewrote it to
ACTUALLY work like that for __DATA.__bss without the marker stuff, and
then I actually got an Emacs.app that worked!
You can see my changes at:
http://bazaar.launchpad.net/~naesten/emacs/nextstep-stuff/revision/108754
Be warned that the line numbers will probably be way off of emacs trunk
right now, since an earlier commit on my branch deletes largish swathes
of code that wasn't really doing anything useful.

Sorry for lack of response. If you have a patch that fixes this, could
you just send it here please? (The launchpad repo is hard to follow.)

What the status on this. Has this been merged into trunk yet?
When I look at the above launchpad page, I see a commit that seems
completely unrelated.

Nope, 'coz I don't know what "this" is to merge.
(IIUC, this is the reason the hydra OS X builds have been failing for ever.)

Indeed.

The status of this is that I got sidetracked trying to get bzr to do
the equivalent of "git rebase -i", and eventually I stopped messing
with the relevant Mac.
It looks like I did rebase at some point, not remembering that I'd
given a revision-number based link.
The changes are still available on the lp:~naesten/emacs/nexstep-stuff
branch, and I've now also imported the branch into git; you can see it
at http://anonscm.debian.org/cgit/users/naesten-guest/emacs.git/log/?h=nextstep-stuff
or get it using e.g. "git fetch
git://anonscm.debian.org/git/users/naesten-guest/emacs.git
nextstep-stuff".
(*Most* of the changes on that branch actually seem to be in unexmacosx.c.)
I have not, however, rebased the branch since it's abandonment; it's
still based on emacs-24.1-1709-g2faa523
I could attempt to rebase at least some of this (I don't expect it
will all rebase cleanly), but I'd have to find a place to set up the
iMac in order to do this properly.

Yes, and IIRC from the last time I looked, most were stylistic/cosmetic,
so I gave up trying to find the minimum one that might fix this bug.
If you find it, please just send it as a patch, against whatever Emacs
version (obviously trunk would be preferable), and we'll try to figure
it out.

If I understand that branch correctly, the attached patch should suffice
to port to GCC 4.6+ on OS X. It's relative to trunk bzr 117895. I
don't have easy access to OS X to try it, though. Peter and/or Samuel,
does it work for you?

You can always install it to trunk and see if the hydra os x build
starts working. :)
I think this is why it has been failing "for ever".

OK, thanks, I gave that a shot in trunk bzr 117896.

I decided to make it simple for me and applied your patch to the sources of emacs-24.3.93 – and it works with GCC 4.6.4! See here:

Thanks for checking. This is not a regression, so it doesn't need to be
applied to the emacs-24 branch. However, perhaps we should do so
anyway, as the patch is localized to OS X, and not working with GCC
4.6.0 (dated 2011) or later is a reasonably big deal.
Stefan, what do you think?

On Mac OS X 10.6.8, Snow Leopard, with intel Core2 hardware your patch works with GCC 4.6.4, 4.7.3 and 4.8.2. Although this is 64-bit hardware I built GNU Emacs as a 32-bit application with wide ints. If you want I can check with 64-bit builds, for which I first would need to build and install the compilers (the 32-bit software comes the Fink Project which starter 32 bit, the 64-bit software comes from the MacPorts project). I could also check with other versions of GNU Emacs, even with GNU Emacs 24.1.50 – its sources are certainly saved in some (Time Machine) backup…
I started a build on PPC hardware (PowerPC 7447A) on Mac OS X 10.4.11 (Tiger). I'll be able to report after sleep…

Looking at the patch I have no idea how "safe" it is.

OK, thanks, I'll leave emacs-24 alone then. Closing the bug, as it
appears to be fixed in the trunk.

I didn't mean to veto it, but rather that I can't judge whether it's OK
to include it.

I think it is not fixed trunk, because GNU Emacs pretest 24.3.94 does not have it. Trying to compile on PPC Mac OS X 10.5.8 (Leopard) with GCC 4.9.1 I got:

If I understand you correctly, you're saying that GNU Emacs 24.3.94 has the bug,
and that the bug went away when you applied the patch (attached), and that we
should therefore backport this patch to the emacs-24 branch. Is that what you
meant? If so, Stefan, OK if I do that?

Exactly! I cannot check whether trunk, GNU Emacs 25.0.50, can be compiled because I get an error when I try to build with GCC 4.8.3 or any other C compiler, except GCC 4.0:

Did this bug affect 24.3 as well?

The little bug that I fixed in trunk bzr 118056 was present only in the trunk;
it's never been in the emacs-24 branch. I think this little bug was introduced
in trunk bzr 117587 on 2014-07-27.
Bug#9927 itself affects 24.3 (and 23) as well. Apparently Emacs has been
unbuildable with GCC 4.6+ for quite some time on OS X. This bigger bug was
fixed in trunk bzr 117896, but that fix was apparently too late for the Emacs
24.4 cutoff.
