This suspiciously looks like a sandbox issue: ./temacs --batch --load loadup bootstrap Unable to trace static ELF: ./temacs: ./temacs --batch --load loadup bootstrap Can you try again with FEATURES="-sandbox -usersandbox", and if this succeeds, with sandbox downgraded to version 2.10? First result: FEATURES="test -sandbox -usersandbox" USE='X Xaw3d -acl alsa -athena -dbus dynamic-loading -games -gconf -gfile gif -gpm gsettings -gtk -gtk3 -gzip-el -imagemagick inotify -jpeg -kerberos -libxml2 livecd -m17n-lib motif -pax_kernel -png sound source ssl svg tiff -toolkit-scroll-bars -wide-int -xft -xpm -zlib' emerge -1 =app-editors/emacs-25.3 This works.

Patch for emacs-25.3.ebuild
Please try if unsetting LD_PRELOAD fixes it, as in this patch for emacs-25.3.ebuild?

build.log
Sorry for the mess, but it is a actually not fixed. The configuration I tested was sadly the one that failed because of missing libXpm before (bug 647242). The problem actually is still there. I'll run the -sandbox tests again.

Loading emacs-lisp/backquote... Loading subr... Loading version... make[1]: *** [Makefile:737: bootstrap-emacs] Bus error So do I understand this correctly, it also fails with sandbox disabled via FEATURES? Exactly. Can you try again with sys-apps/sandbox-2.13 and emacs-25.3-r3? Same error. (In reply to Rolf Eike Beer from comment #12) > Same error. Does it output that "Unable to trace static ELF" message, too?

build.log with sandbox 2.13 and emacs-25.3-r3
Basically the same errors as before AFAICT.
Very strange. "Unable to trace static ELF" is a message from sandbox so it shouldn't appear.
Can you add -ggdb to your CFLAGS and run that failing temacs command under gdb (i.e., in ${S}/src: "gdb temacs" and "run --batch --load loadup bootstrap")? So we can get a backtrace and see where it segfaults?

emacs-25.3-mark_memory.patch
Please try if attached patch (extracted from upstream bug) fixes the problem.
I can confirm that the patch from https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30855#23 fixes the build for me for both 25.3-r3 and 26.0.91.
