Is this reproducible? Please attach the full build.log.
Created attachment 365494 [details] emerge output
Yes, this error is reproducible and always the same
(In reply to Clemens Schüller from comment #2) > Created attachment 365494 [details] > emerge output With -s in MAKEOPTS this is not so helpful. Anyway, using the same CFLAGS and USE flags as you, I still cannot reproduce the problem. Can you try to compile emacs with ccache turned off?
The same error, after i deleted -s from makeopts and turning off ccache.
Not much I can do here when I can't reproduce the bug. Some ideas: - Compile with -ggdb and produce a core dump, in order to find out where exactly it crashes. - Does app-editors/emacs-24.3-r2 build? - Does the bug also occur on a plain Gentoo system, or is it caused by something that is specific to Sabayon (like kernel, gcc, or glibc)?

I will try it ASAP ;-)
Created attachment 365624 [details] strace output from emerge
(In reply to Clemens Schüller from comment #7) > > - Compile with -ggdb and produce a core dump, in order to find out where > > exactly it crashes. > > How can I enable the debug feature? Not sure if this answers your question, but add -ggdb to CFLAGS, enable core dumps with "ulimit -c unlimited", and after the crash inspect the core dump with "gdb /path/to/temacs /path/to/core". You can obtain a backtrace with the command "bt full" in gdb.
Thanks, i try it, as i find time for it. I added a strace output - is this a help to solve the error?

So it occurs in unexec and looks similar to bug 411439 or bug 456970. It could be a kernel issue, or something different. Can you try if you can compile emacs with the following workaround: $ cat /proc/sys/kernel/randomize_va_space # take a note of the output $ echo 0 >/proc/sys/kernel/randomize_va_space $ emerge app-editors/emacs-vcs $ echo <the previous value noted above> >/proc/sys/kernel/randomize_va_space If it does compile with this, then it is likely that the problem is related to some kernel setting, either in sabayon, or in your own kernel options.
Thanks for Your feedback I'll check it out on next sunday, because I've currently no access to the PC, which have this bug
Hello! After a long time of no time i found the error: It was the wrong gcc config.
