From: Elric Milon <emacs <at> whirm.eu> To: bug-gnu-emacs <at> gnu.org Subject: Commit b88e9cded7ae3756e3a2ec4a23e8df352a0239f9 breaks emacs dumping for me Date: Mon, 01 Feb 2016 14:37:21 +0100
Trying to build current master failed while dumping emacs, so I ran a
git bisect with the following script to find the culprit:
8<------------8<------------8<------------8<------------8<------------
set -ex
./autogen.sh
./configure --prefix $(readlink -fe $PWD/../inst) \
--enable-link-time-optimization \
--without-pop \

--without-xaw3d \
--without-selinux \
--with-file-notification=yes \
--with-modules \
--with-cairo \
--without-pop \
--with-x
make -j$(grep processor /proc/cpuinfo |wc -l ) bootstrap
make -j$(grep processor /proc/cpuinfo |wc -l )
make install
8<------------8<------------8<------------8<------------8<------------
And this is the failure message:

commit b88e9cded7ae3756e3a2ec4a23e8df352a0239f9

malloc.h hygiene
This attempts to future-proof Emacs a bit against possible glibc
changes, by having Emacs use <malloc.h> declarations rather than
coding them up by hand. Problem noted by Florian Weimer in:
https://sourceware.org/ml/libc-alpha/2016-01/msg00777.html
Implement this mainly by moving malloc.h-related functions from
emacs.c (which does not include <malloc.h>) to alloc.c (which does).
* src/alloc.c (my_heap_start) [DOUG_LEA_MALLOC || GNU_LINUX]:
New function.
The remaining changes to this file apply only if DOUG_LEA_MALLOC.
(alloc_unexec_pre, alloc_unexec_post): New functions.
(malloc_initialize_hook): Use my_heap_start and alloc_unexec_post.
(__MALLOC_HOOK_VOLATILE): New macro, if not already defined.
(__malloc_initialize_hook): Use it.
(malloc_state_ptr, malloc_initialize_hook, __malloc_initialize_hook):
Move here from ...
* src/emacs.c: ... here.
(malloc_get_state, malloc_set_state): Remove extern decls.
(my_heap_start) [DOUG_LEA_MALLOC || GNU_LINUX]: Remove static var.
All uses changed to similarly-named new function.
(Fdump_emacs): Use new functions alloc_unexec_pre, alloc_unexec_post.
* src/lisp.h (my_heap_start, alloc_unexec_pre, alloc_unexec_post):
New decls.

I've tried building master on two different up to date Debian SID
machines with similar results.
Note that I tried disabling `randomize_va_space` and running it with
`setarch x86_64 -R` and it failed too.
Thanks!
