Description

There seems to be some stuff going on here: did those sandbox errors appear with the upgrade of coreutils, or are they unrelated? Cold you also try to crash sort outside of portage and maybe even attach a backtrace of said segfault? Does downgrading to coreutils-8.5 make the problems go away? For me said versions of coreutils works fine on hardened, and at this stage I am unsure about if sort really is the culprit or if there is something more serious going on. what does `sort` misbehavior have to do with the sandbox output ? I have the same problem (but reproducible while building proprietary software) here on my machine since coreutils was upgraded. If I use coreutils < 8.7 I have no problems.

Downgrading to coreutils-8.5 solve the proble (or compile coreutils-8.7 without optimization CFLAGS="-g -pipe" CXXFLAGS="${CFLAGS}"). # gdb sort -c core -d /var/tmp/portage/sys-apps/coreutils-8.7/work/coreutils-8.7/src/ GNU gdb (Gentoo 7.2 p1) 7.2 Copyright (C) 2010 Free Software Foundation, Inc.
