gcc segfaults when building x11-libs/qt-4.3.2 using the -O2 CFLAGS. Reproducible: Always Steps to Reproduce: 1. Enter CFLAGS="-O2 -march=athlon64 -pipe" in /etc/make.conf 2. emerge x11-libs/qt-4.3.2 3. See gcc segfault 4. Enter CFLAGS="-march=athlon64 -pipe" in /etc/make.conf 5.

I just tried to reproduce this in a stable chroot and I don't get an ICE with the attached preprocessed output. If you run gcc on the preprocessed output you attached (with the flags you specified), do you get an ICE? Does GCC ICE in the same spot every time? I'm attempting to compile qt with the flags you specified as well.
Exactly the same spot. (I just tried it again.) The prepared source file will of course get a new filename every time. g++ -c -o unixmake2.o -O2 -march=athlon64 -pipe -pipe -DQMAKE_OPENSOURCE_EDITION -I. -Igenerators -Igenerators/unix -Igenerators/win32 -Igenerators/mac -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/src/corelib/arch/generic -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/include -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/include/QtCore -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/include -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/include/QtCore -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/src/corelib/global -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/src/script -DQT_NO_PCRE -DQT_NO_TEXTCODEC -DQT_NO_UNICODETABLES -DQT_NO_COMPONENT -DQT_NO_STL -DQT_BUILD_QMAKE -DQT_NO_COMPRESS -I/var/tmp/portage/x11-libs/qt-4.3.2/work/qt-x11-opensource-src-4.3.2/mkspecs/linux-g++ -DHAVE_QCONFIG_CPP -DQT_NO_THREAD -DQT_NO_QOBJECT -DQT_NO_GEOM_VARIANT generators/unix/unixmake2.cpp generators/unix/unixmake2.cpp: In member function 'void UnixMakefileGenerator::writeMakeParts(QTextStream&)': generators/unix/unixmake2.cpp:947: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

are you removing your portage tmpdir in between tries? I think this is more of a local issue than a widespread one. We've had lots of ICEs in qt throughout the years, but they've pretty much always ended up being isolated scenarios.
"are you removing your portage tmpdir in between tries?" In Comment #6 the /var/tmp directory was cleaned between trials. "I think this is more of a local issue than a widespread one." Maybe. Am I not supposed to provide bug reports if there is anything that would make me think that it could be local? (Trying to adhere to best practices here.) "We've had lots of ICEs in qt throughout the years, but they've pretty much always ended up being isolated scenarios." I'm probably a pain somewhere, but I believe that a piece of software (g++) should not be allowed to _Segmentation fault_ due to a combination of data input. In this case '-O2 -march=athlon64 -pipe -c blah.ii'. I wouldn't report this if g++ said that it couldn't compile the file under certain circumstances. But I do report that it _SegFaults_, which IMHO no core system component should be allowed to do.
you cant work around crappy hardware in software
@SpanKY Lacking more precision, I guess "crappy hardware" refers to AMD64. A couple of days ago, a colleague of mine told me that he's having the very same problem in his AMD64 setup. I told him to sign up here, but he didn't want to risk getting yelled at for adding a "Me too" entry. Anyway, I will close this report as hardware related, CANTFIX. "Don't use Linux/Gentoo/gcc under AMD64." Sorry for all the mess I've apparently created. I'll be more careful in the future.
no one said amd64 sucks. i run amd64 as my main machines and they work fine. i was pointing out your misinterpretation of Caleb's comments.

My solution so far has been to mask qt-4.3.2 and above, I'm sure this will only work for so long. It's nice to know that I could probably remove the -O2 CFLAG. Is there something else I can look at to try to figure out what is going wrong? My computer errors in the same exact place.
