Problem is still there in xemacs-21.4.15-r3.
I gave it another try, after switching from hardened gcc to vanilla (3.4.4). Now xemacs compiles just fine. So it seems to be a hardened toolchain issue.
affirmed hardened@gentoo.org added to CC list
Looks like something doesn't like PIE. Try: CFLAGS="-nopie" emerge xemacs with the hardened compiler and report back, please.
Okay, the "-nopie" did it :) ==> CFLAGS="-nopie -march=athlon64 -O3 -ffast-math -funroll-all-loops -fpeel-loops -ftracer -funswitch-loops -funit-at-a-time -pipe -fomit-frame-pointer" CXXFLAGS="-nopie -march=athlon64 -O3 -ffast-math -funroll-all-loops -fpeel-loops -ftracer -funswitch-loops -funit-at-a-time -pipe -fomit-frame-pointer" emerge -vD xemacs Can the ebuild file / source code altered that way that giving "-nopie" as CFLAG is not needed?
Adding -nopie to CFLAGS works for me too.
Thanks everyone for the feedback, it's good to know that this issue is solved with the -nopie flag in CFLAGS. This is not something that can be put in the ebuild automatically, though, because it would silently subvert the purpose of being on a hardened profile. I will put a note about this issue in the ebuild, though. I'm leaving this bug open for now as the real problem should still be solved. It would be great if someone on a hardened profile could do a bit more investigating to see if the actual cause of this crash be be found and fixed.
Ah; this one had dropped into the mists of time for us. The '-nopie' confirms it's an incompatibility with the hardened toolchain. If that incompatibility turns out to be too much trouble to solve, adding: filter-flags -fPIE to the ebuild will disable it. However before that happens I wanted to determine what is causing the problem and whether it can be easily fixed.
ok; what's happening is that src/vm-limits.c:check_memory_limits is issuing a warning via (*warn_function)(), and the data used by the warning function has not been initialised (Vpending_warnings in eval.c) because src/eval.c:vars_of_eval hasn't yet been called. This means it dereferences a null object which causes a segfault. This is all because xemacs is doing it's own thing to work out memory limits. In particular, it's using 'environ' to find the base of the heap (src/sysdep.c), which not a particularly good way of doing it - there's nothing to say that environ is at the bottom of the heap, which is what xemacs is assuming, and it's simply false for PIEs. This was fixed for emacs itself, which (at least when built PIE) uses the 'data_start' symbol. Of course really there are two problems: (1) the use of 'environ' is relying on undefined behaviour (2) the warning function is using un-initialised data. I suggest chatting to upstream about it - perhaps if they're planning to import more recent code from the emacs base (src/sysdep.c is (c) 1995 in xemacs, (c) 2001 in emacs) this issue can be resolved in xemacs the same way it was in emacs.
*** Bug 63358 has been marked as a duplicate of this bug. ***
I've (finally...) posted a note about this to the XEmacs development list.
still on xemacs-21.4.21-r1 ... updating title... any response from upstream?
No response. XEmacs development is very slow at the moment, so I don't really expect this to get fixed any time soon.

I encountered the same bug with xemacs-21.4.22-r1 on PPC hardened, gcc-4.4.4. I tried the solution given for Emacs (see bug #345001), relying on changing the value of /proc/sys/kernel/randomize_va_space during the build, and it seems to work. The advantage over the NOPIE trick is that the resulting binary still have the PIE things inside. So, this is how I did it: <<<<<<<<<< # cat /proc/sys/kernel/randomize_va_space 2 # echo 0 > /proc/sys/kernel/randomize_va_space # emerge --oneshot xemacs # echo 2 > /proc/sys/kernel/randomize_va_space >>>>>>>>>> The value '1' did not work, but '0' is fine. I don't know the difference and need to read a few things about the randomize_va_space kernel parameter. Could that be included in the ebuild without side effects? <<<<<<<<<<<<<<<<<<<<<<<<< Portage 2.1.9.25 (hardened/linux/powerpc/ppc32, gcc-4.4.4, glibc-2.11.2-r3, 2.6.28-hardened-r9 ppc) ================================================================= System uname: Linux-2.6.28-hardened-r9-ppc-7447A,_altivec_supported-with-gentoo-1.12.14 Timestamp of tree: Sat, 25 Dec 2010 15:15:03 +0000 app-shells/bash: 4.1_p7 dev-lang/python: 2.6.5-r3, 3.1.2-r4 dev-util/cmake: 2.8.1-r2 sys-apps/baselayout: 1.12.14-r1 sys-apps/sandbox: 2.4 sys-devel/autoconf: 2.13, 2.65-r1 sys-devel/automake: 1.9.6-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.4.4-r2 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.10 sys-devel/make: 3.81-r2 virtual/os-headers: 2.6.30-r1 (sys-kernel/linux-headers) ACCEPT_KEYWORDS="ppc" CBUILD="powerpc-unknown-linux-gnu" CFLAGS="-O2 -mcpu=7450 -maltivec -mabi=altivec -fno-strict-aliasing -pipe" CHOST="powerpc-unknown-linux-gnu" CXXFLAGS="-O2 -mcpu=7450 -maltivec -mabi=altivec -fno-strict-aliasing -pipe" FEATURES="assume-digests binpkg-logs distlocks fixlafiles fixpackages news parallel-fetch protect-owned sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="fr en" MAKEOPTS="-j2" USE="acl altivec apache2 bash-completion berkdb bzip2 cdr cgi clamav cli cracklib crypt cxx dbm dri dvd dvdr fastcgi gd gdbm gif gmp gnutls gpm graphviz hardened hardenedphp iconv imagemagick imap jpeg mbox modules mpeg mudflap mule ncurses nptl nptlonly openmp pam pcre pdf perl pic png posix postgres ppc python readline session spell ssl svg symlink sysfs tcpd tetex tiff urandom xml xorg xpm zlib" ALSA_CARDS="aoa aoa-fabric-layout aoa-onyx aoa-soundbus aoa-soundbus-i2s aoa-tas aoa-toonie powermac" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic auth_digest authn_anon authn_default authn_file authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache dbd deflate dir env expires file_cache filter headers ident imagemap include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif so speling status unique_id userdir usertrack vhost_alias cgi fcgid" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="ncurses text" LINGUAS="fr en" PHP_TARGETS="php5-3" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="radeon fbdev dummy vga" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, LANG, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS >>>>>>>>>>>>>>>>>>>>>>>>>
*** Bug 377515 has been marked as a duplicate of this bug. ***
same problem here ( hardened toolchain too ) but on app-editors/xemacs-21.4.22-r1 : Testing for Lisp shadows ... make[1]: *** [xemacs.dmp] Segmentation fault make[1]: *** Deleting file `xemacs.dmp' make[1]: Leaving directory `/var/tmp/portage/app-editors/xemacs-21.4.22-r1/work/xemacs-21.4.22/src'
And also with xemacs-21.4.22-r2 on i686 there is the same problem.
It would be interesting to know if xemacs 21.5.x has the same problem. So far I haven't seen reports about that version yet.
I am still getting the same behavior on 21.5.31 as with previous versions: with the hardened toolchain the ebuild either runs my CPU up to 100% and hangs, or segfaults almost immediately, depending on the state of PaX in my kernel. CFLAGS="-nopie" fixes the build.

The newer emacs have a workaround for hardened. Some one willing to test the workarond?

FWIW I can compile at my tinderbox app-editors/emacs-24.5-r1 w/o caring about -nopie (hardened 64 bit Gentoo). But I do still run reliable into bug #540818, which can just be circumvented by emerging xemacs with -nopie.
The xemacs ebuilds have been modified to use -nopie which makes them build. This ticket is left open as a reminder, for nudging upstream or anyone else who has the know how, to solve the bigger problem with allowing XEmacs to be built with PIE.
