Meanwhile, I have updated several other Gentoo systems (32 and 64 bit) which all worked well. It's just that one system which brings that error. I have also found https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79827 and made "ulimit -s 32768" (instead of 8192), but to no avail. The only difference is the kernel (4.0.5 on the old system; all others have 4.14.83 oder even some 5.x kernel). On the other hand: the difference between gcc 11.2.1 (which works fine) and 11.3.0 shouldn't be that big?! -Matt

It seems that the command line to compile "genautomata" contains useful information to understand the cause. Can you find it in the GCC compile logs ? With that you may open a bug in Gentoo or GCC Bugzilla. Best regards Mickaël Bucas
[gentoo-user] Does gcc 11.3 need a special/new kernel version?
Hi, I have a rather old server which I still keep alive (u never know if it's needed again), so I update all packages about once a month with emerge -aNDuv --keep-going --backtrack=999 --with-bdeps=y @world which works fine - until now. I can't upgrade gcc from 11.2.1 to 11.3.0 because of make[3]: Entering directory '/var/tmp/portage/sys-devel/gcc-11.3.0/work/build/gcc' build/genautomata /var/tmp/portage/sys-devel/gcc-11.3.0/work/gcc-11.3.0/gcc/common.md /var/tmp/portage/sys-devel/gcc-11.3.0/work/gcc-11.3.0/gcc/config/i386/i386.md \ insn-conditions.md > tmp-automata.c make[3]: *** [Makefile:2456: s-automata] Error 139 make[3]: Leaving directory '/var/tmp/portage/sys-devel/gcc-11.3.0/work/build/gcc' make[3]: *** Waiting for unfinished jobs and dmesg says [ 1297.247619] genautomata[3301]: segfault at bfea1ffc ip b76bb23b sp bfea2000 error 6 in genautomata[b76b1000+44000] Granted, it is still kernel 4.0.5, but I don't want to go through the trouble of installing a new kernel on the old system. But the old kernel is the only thing I can think of that could be causing the problem...?! Possibly there was a discussion about this, in the year 2008: https://gcc.gnu.org/pipermail/gcc-patches/2008-November/251389.html but I don't understand what's it all about, and how could I modify emerge to work around the problem. gcc is the only package which won't upgrade - everything else works fine (including glibc 2.34-r13 and all the other stuff). Any hints? Thanks, -Matt
