eix fells out with sigsegv signal and actually says that I should do a bugtrace for it (what a nice thing...) Reproducible: Always Steps to Reproduce: 1. no real special steps. It started happening after I switched my home server to the hardened profile Actual Results: program falls out with sigsegv signal Expected Results: well, actually to find or don't find the program in the eix cash Stack trace: ~ # gdb --args eix telnet GNU gdb 6.6 Copyright (C) 2006 Free Software Foundation, Inc.

Can you try with the latest eix version please?
it is already the latest version: ~ # eix -V eix 0.9.9 (gcc-3.4.6, i686-pc-linux-gnu) ~ # ls -al /etc/make.profile lrwxrwxrwx 1 root root 38 Aug 1 14:29 /etc/make.profile -> /usr/portage/profiles/hardened/x86/2.6
Also tried going up to 0.9.10 - same problem. Downgrading to 0.8.8 brought an interesting thing - update-eix fails for the same reason: sigsegv and you can't do anything. It would not update the cash..

though the solution of changing the CXXFLAGS (and CFLAGS) flags to -02 or -01 didn't work in my case. The only way does work is when i'm compiling with vanila gcc... server ~ # gcc-config -l [1] i686-pc-linux-gnu-3.4.6 [2] i686-pc-linux-gnu-3.4.6-hardenednopie [3] i686-pc-linux-gnu-3.4.6-hardenednopiessp [4] i686-pc-linux-gnu-3.4.6-hardenednossp [5] i686-pc-linux-gnu-3.4.6-vanilla * [6] i686-pc-linux-gnu-4.1.2
I installed gcc-3.4.6-r2 with USE=hardened and kept to receive sigsev with CXXFLAGS=''. This time it was not std::unique() (for which I had built a workaround) but std::sort() which randomly caused the error (not very reproducable). I will not try to debug this any further, because I am rather sure that it is the compiler/library which is broken and not eix: Probably the failing of std::unique() and std::sort() are only symptoms of some other compiler-internal bug. However, when setting "CXXFLAGS=-O2" the error vanishes. Therefore, I almost cannot believe: (In reply to comment #5) > though the solution of changing the CXXFLAGS (and CFLAGS) flags to -02 or -01 > didn't work in my case. Already the fact that CXXFLAGS="" although CFLAGS is set in your emerge --info is somewhat strange; are you sure that you wanted this? Maybe for some reason you have 'export CXXFLAGS=""' in your shell startup scripts which overrides the setting in /etc/make.conf? Or maybe you use only shell variables and have forgotten to "export CXXFLAGS"? Can you really see the text "-O2" in the compiler calls when you emerge eix?
(In reply to comment #6) found the problem... in make.conf parameters from CFLAGS weren't passing down to CXXFLAGS probably due to change from "(" to "{" brackets: CXXFLAGS="${CFLAGS}" is the correct version. My bad there... After changing that it does compile fine with -02 Tried with -03 - works fine. I guess it was a problem of a simple brackets. My apologies for you having to spend time on this..
