Hi.

(Some response to #6031, http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6031)

I'm trying to compile Emacs from BZR using gcc 4.5.0
$ bzr revno
100035

Compilation went ok but when I try to run Emacs it segfault'ed.

Here what I see running compiled Emacs in gdb:

The same happens with emacs-23.1.96 (taken from

In both cases configure script was run with options:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
--mandir=$HOME/tmp/emacs --libexecdir=/usr/lib --with-xpm --with-jpeg
--with-tiff --with-gif --with-png --with-rsvg --with-x-toolkit=gtk
--with-xft --with-libotf --with-dbus --without-sound
--enable-maintainer-mode

OS: Archlinux x86_64
GCC: 4.5.0

I also tried to compile Emacs (BZR) with gcc 4.4.3 ( the same distro
but a bit outdated). After compilation I managed to run Emacs
(terminal session).

Seems that with gcc 4.4
(http://bugs.gentoo.org/show_bug.cgi?id=317187) Emacs could be
compiled and run without errors.
