Hello!

	In GNU Emacs 24.3.50.1 (powerpc-apple-darwin9.8.0, X toolkit, Xaw3d  
scroll bars)
	 of 2013-01-21 on Latsche.local
	Bzr revision: 111577 dmantipov@yandex.ru-20130121170109-qsz6nomnl47c53nx

compiles and builds fine, but when I add --with-wide-int to the

	unexec: find_emacs_zone_regions: too many regions
	make[2]: *** [bootstrap-emacs] Error 1
	make[2]: Leaving directory `.../emacs-24.3.50/src'

It happens for both the X11 client and the NS variant. If I substitute  
-Os with -O0 both compile.

Thanks, does the following fix things for you, and if so, how many
regions does Emacs report when dumping?

I did not try that patch yet – because I was compiling GNU Emacs from  
the same code basis as yesterday, now without the bootstrap option.  
And it builds with -Os, and if fails when building the bootstrap  
targets with -Os!

I saved all *compilation* buffers. Comparing "make bootstrap with -Os"  
with "make with -Os" leads, when I leave away the initial bootstrap  
paraphernalia, to these "major differences:

make bootstrap:
	make[2]: Leaving directory `.../emacs-24.3.50/lib'
	cd lib-src && make all -w                         \
	  CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-common - 
Os -mcpu=7450 -mtune=G4' CPPFLAGS='-I/sw/include' \
	  LDFLAGS='-L/sw/lib -v -Wl,-v -Wl,-dead_strip_dylibs -Wl,- 
bind_at_load -Wl,-t -L/usr/X11/lib' MAKE='make'
	
	make[2]: Leaving directory `.../emacs-24.3.50/lib-src'
	boot=bootstrap-emacs;                         \
	if [ ! -x "src/$boot" ]; then                                     \
	    cd src; make all -w                                   \
	      CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-

	fi;

make:

	cd lib-src && make all                          \

	if [ ! -x "src/$boot" ]; then                                     \
	    cd src; make all                                    \
	      CC='gcc -std=gnu99' CFLAGS='-g -ggdb3 -H -pipe -fPIC -fno-

bind_at_load -Wl,-t -L/usr/X11/lib' MAKE='make'  
BOOTSTRAPEMACS="$boot"; \
	fi;

which certainly is not significant. But then there are some during the  
dumping step:

make bootstrap:
	34 LC_LOAD_DYLIB          52
	 0x14fc080 (sz:   0x2cf1/  0x3f0a)
	 0x1400000 (sz:  0x6b5e4/ 0xfc080)
	 0x27f8000 (sz:   0x6d58/  0x7f80)
	 0x2000000 (sz: 0x6d5600/0x7f8000)
	 0x17f8000 (sz:   0x3fff/  0x5000)


make:
	34 LC_LOAD_DYLIB          52
	 0x14fc080 (sz:   0x2558/  0x3f0a)
	 0x1400000 (sz:  0x2e950/ 0xfc080)
	 0x27f8000 (sz:   0x63b8/  0x7f80)
	 0x2000000 (sz: 0x639917/0x7f8000)
	 0x13f3000 (sz:   0x3fff/  0x5000)

This is just a snapshot from the start, more and subtle differences  
follow like for example (same "line numbers"):

	 0x17b0000 (sz:   0x3fff/  0x5000)
	 0x17a9000 (sz:   0x63c7/  0x7000)
	 0x17a2000 (sz:   0x63bb/  0x7000)
	 0x179d000 (sz:   0x3fff/  0x5000)

vs.

	 0x17d4000 (sz:   0x3fff/  0x5000)
	 0x13d2000 (sz:   0x3fff/  0x5000)
	 0x17cd000 (sz:   0x63bb/  0x7000)
	 0x13cd000 (sz:   0x3fff/  0x5000)

Before I'll try the patch I'll make bootstrap with -O0 so see whether  
this works – unless you recommend something different.

BTW, how do I count these regions? On Mac OS X this count is not  
directly reported and I have no idea how determine the number.

My tries today were 'make clean', configure ..., make.

Sorry, I don't use OS X, I'm just trying to help remotely.
I'd just take the number of text lines that look like
those regions, as Emacs appears to output one line per region.

After the text "Dumping under the name emacs" follows

--- List of All Regions --- = 153 lines
+
--- List of Regions to be Dumped --- = 144 lines
followed by
--- Header Information ---

So it's presumingly 397 regions, less than the 400.

The 'make bootstrap' with -O0 fails as well.

I'm going to patch now…

With this patch applied, optimisation at -O0, 'make bootstrap'  
delivers 124 + 116 lines plus 447 lines after the lines

	33 LC_LOAD_DYLIB          56
	34 LC_LOAD_DYLIB          52

The build now fails with:

Presumably this line in unexmacosx.c needs to be changed:

static unsigned long text_seg_lowest_offset = 0x10000000;

I'd try changing it to (say) 0x20000000, and then see what
Emacs says is the "Lowest offset of all sections in __TEXT segment".

This change leads to the same failure. The requested value ranges from  
0x1218 (from my tries with Xaw3d variant and GCC 4.2, yesterday) up to  
0x20a0 (NS variant with GCC 4.0, last summer). The last (failed)  
compilation reports 0x139c.

I have two package managers installed on my Mac, Fink and MacPorts, to install all the necessary and up-to-date libraries and software. Until now I was using libraries from Fink. An hour ago I configured, after a 'make distclean', to use MacPorts – and GNU Emacs builds as X client with wide ints. So I am considering that Fink is a bit defective…

Rebuilding dozens of packages can take days presumingly!

I found the reason for the different behaviour: 'make bootstrap' seems  
to throw away the Makefile(s) built by configure and it then runs  
config.status. Without setting PATH the wrong utilities are found and  
the built can become a mix of system, Fink, and MacPorts software.  
This cannot work.

To 'make bootstrap' I'll have to rename Fink's /sw or MacPorts' /opt –  
which also means that I won't have access to all compilers installed.

I have indeed undone all patches to src/unexmacosx.c. Within the  
clearly set build environments for configure, make, make install GNU  
Emacs builds without problems. I updated the sources and still no  
problem. The real problem is that 'make bootstrap' does not honour the  
previous configure step and tries something that is bound to fail. If  
this behaviour continues, the sequence of make distclean, configure,  
make, make install seems to be a valid work-around.

My bug report was wrong: I did not see what 'make bootstrap' was  
really performing.
