Uhm this gets fun. I'll try to add 1.9.2rc1..
Upstream claim this is a GCC issue with >= -O2: http://redmine.ruby-lang.org/issues/show/ The explanation for that is in Japanese which is really really really really really really really really really great.
Oh, far far on the bottom, there's some English.. "I'm suspecting that there is a bug in gcc 4.4.1. A local variable of caller seems to be changed by callee if the callee is inlined. You can avoid this issue by using -O0 or -O1."
using -O0 fixes the problem for me on x86 -O1 did not fix it. I have not seen the problem on amd64. gcc version 4.4.4 (Gentoo 4.4.4-r1 p1.0, pie-0.4.5)
We no longer have ruby 1.9.1 versions in the tree. Is this problem still present with ruby 1.9.2?
(In reply to comment #7) > We no longer have ruby 1.9.1 versions in the tree. Is this problem still > present with ruby 1.9.2? I compiled ruby 1.9.2p0 with gcc 4.4.5 and "-O2 -g" option on x86 machine, and no problem occurred. In addition, the bug is treated as a problem about ruby1.9.1 in ruby bug tracking system (http://redmine.ruby-lang.org/issues/2727). I also googled, and couldn't find any reports concerned to the bug on ruby 1.9.2. So, I guess the bug is not present in ruby 1.9.2. emerge --info -------------------- Portage 2.2.0_alpha58 (default/linux/x86/10.0/desktop, gcc-4.4.5, glibc-2.13-r4, 3.0.4-gentoo i686) ================================================================= System uname: Linux-3.0.4-gentoo-i686-Genuine_Intel-R-_CPU_T2300_@_1.66GHz-with-gentoo-2.0.3 Timestamp of tree: Fri, 16 Sep 2011 22:00:01 +0000 distcc 3.1 i686-pc-linux-gnu [disabled] app-shells/bash: 4.2_p10 dev-java/java-config: 2.1.11-r3 dev-lang/python: 2.7.2-r3, 3.2.2 dev-util/cmake: 2.8.5-r2 dev-util/pkgconfig: 0.26 sys-apps/baselayout: 2.0.3 sys-apps/openrc: 0.9.3-r1 sys-apps/sandbox: 2.5 sys-devel/autoconf: 2.13, 2.68 sys-devel/automake: 1.11.1-r1 sys-devel/binutils: 2.21.1-r1 sys-devel/gcc: 4.4.5 sys-devel/gcc-config: 1.4.1-r1 sys-devel/libtool: 2.4-r1 sys-devel/make: 3.82-r1 sys-kernel/linux-headers: 2.6.39 (virtual/os-headers) sys-libs/glibc: 2.13-r4 Repositories: gentoo naota sunrise grafi Installed sets: ACCEPT_KEYWORDS="x86 ~x86" ACCEPT_LICENSE="*" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -pipe -mtune=native -march=native -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -pipe -mtune=native -march=native -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs distlocks ebuild-locks fixlafiles fixpackages news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS=""
Thanks for the feedback. I'm going to close this as obsolete then. Please reopen if this problem still occurs with ruby 1.9.2.
