I'm developing a software package, and while building, under uncertain circumstances, g++ crashes, showing this on screen: -------------------- g++ -o usr/share/motorsport/Threadable.os -c -g -O0 -ggdb3 -Wall -Wno-deprecated -ansi -pedantic --coverage -fprofile-arcs -ftest-coverage -isystem usr/include/boost-1_35 -isystem usr/include/boost-1_35 -fPIC -Iusr/include -Iusr/include/boost-1_35 -Iusr/include/boost-1_35 -Iusr/include/bullet usr/share/motorsport/Threadable.cpp usr/share/motorsport/Threadable.cpp: In function '(static initializers for usr/share/motorsport/Threadable.cpp)': usr/share/motorsport/Threadable.cpp:129: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. Preprocessed source stored into /tmp/ccKC3cRo.out file, please attach this to your bugreport. scons: *** [usr/share/motorsport/Threadable.os] Error 1 scons: building terminated because of errors. -------------------- Attached is the aforementioned cKC3cRo.out file. The crash happens always, provided i don't change the piece of source code i'm trying to compile. If needed, i can provide the whole source code and libs i'm using, but it totals 1.2GiB, since it includes builds/source code of third party libs (using specific svn revisions, of libs like boost, bullet, ogre, ogrecollada, fcollada, scons, unittest-cpp). Reproducible: Always Steps to Reproduce: 1.Run the g++ command shown above Expected Results: The file should compile, or at least complain about syntax errors, link errors, or whatever. $ uname -a Linux 1ksurvivor 2.6.25-gentoo-r7 #1 SMP Thu Aug 21 15:15:49 CEST 2008 i686 Intel(R) Core(TM)2 CPU 4300 @ 1.80GHz GenuineIntel GNU/Linux $ g++ --version g++ (GCC) 4.1.2 (Gentoo 4.1.2 p1.1) Copyright (C) 2006 Free Software Foundation, Inc.

What do you have for 'emerge -pv =sys-devel/gcc-4.1.2'? I have a system with this gcc: [ebuild R ] sys-devel/gcc-4.1.2 USE="doc fortran mudflap nls (-altivec) -bootstrap -build -d -gcj -gtk (-hardened) -ip28 -ip32r10k -libffi% (-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc -test -vanilla" 50 kB and I can't get your test case to fail. This is what I did, maybe you could try it too to make sure it is equivalent to your original compile: cp ccKC3cRo.out test.cc g++ -c -g -O0 -ggdb3 -Wall -Wno-deprecated -ansi -pedantic --coverage -fprofile-arcs -ftest-coverage test.cc
Also post your emerge --info, which includes some things you didn't mention (such as whether you're running 32-bit or 64-bit, version of glibc, etc)
For the record, right now i'm getting this: $ g++ -c -g -O0 -ggdb3 -Wall -Wno-deprecated -ansi -pedantic --coverage -fprofile-arcs -ftest-coverage test.cc test.cc:2:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.cpp:1:3: warning: style of line directive is a GCC extension /home/stenyak/dev/motorsport//:1:3: warning: style of line directive is a GCC extension <built-in>:1:3: warning: style of line directive is a GCC extension <command line>:1:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.cpp:2:3: warning: style of line directive is a GCC extension In file included from usr/share/motorsport/Threadable.cpp:3: usr/share/motorsport/Threadable.h:5:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.h:7:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.h:9:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.h:11:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.h:13:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.h:15:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.h:79:3: warning: style of line directive is a GCC extension usr/share/motorsport/Threadable.cpp:3:3: warning: style of line directive is a GCC extension In file included from usr/share/motorsport/Threadable.cpp:4: usr/share/motorsport/Exception.h:31:3: warning: style of line directive is a GCC extension Which does not look like a crash of g++ to me... I haven't installed or modified any thing on my system, appart from the source code of my project (which is not mentioned in that g++ cmd line). Do bash environment variables have anything to do?

Does the failure happen exactly as reported every time when you try compiling from your full build tree? Or does it crash at different points? If it is totally repeatable from the full build, what happens when you run the command by itself using original source instead of preprocessed, still repeatable? g++ -o usr/share/motorsport/Threadable.os -c -g -O0 -ggdb3 -Wall -Wno-deprecated -ansi -pedantic --coverage -fprofile-arcs -ftest-coverage -isystem usr/include/boost-1_35 -isystem usr/include/boost-1_35 -fPIC -Iusr/include -Iusr/include/boost-1_35 -Iusr/include/boost-1_35 -Iusr/include/bullet usr/share/motorsport/Threadable.cpp
