just switched over to gcc-4.2.0, since it was marked ~amd64. rebuilt gcc, rebuilt system, both without problems. during a rebuild world, the qt build fails. the error message is below. after switching back to x86_64-pc-linux-gnu-4.1.2 (and making no other changes), the build is successful. Reproducible: Always Steps to Reproduce: 1.update gcc on ~amd64 to gcc-4.2.0 2.emerge qt g++ -shared -Wl,-soname,libQtCore.so.4 -o libQtCore.so.4.3.0 .obj/release-shared/qglobal.o .obj/release-shared/qlibraryinfo.o .obj/release-shared/qnumeric.o .obj/release-shared/qmutex.o .obj/release-shared/qreadwritelock.o .obj/release-shared/qmutexpool.o .obj/release-shared/qsemaphore.o .obj/release-shared/qthread.o .obj/release-shared/qthreadstorage.o .obj/release-shared/qmutex_unix.o .obj/release-shared/qthread_unix.o .obj/release-shared/qwaitcondition_unix.o .obj/release-shared/qbitarray.o .obj/release-shared/qbytearray.o .obj/release-shared/qbytearraymatcher.o .obj/release-shared/qcryptographichash.o .obj/release-shared/qdatetime.o .obj/release-shared/qhash.o .obj/release-shared/qline.o .obj/release-shared/qlinkedlist.o .obj/release-shared/qlistdata.o .obj/release-shared/qlocale.o .obj/release-shared/qpoint.o .obj/release-shared/qmap.o .obj/release-shared/qrect.o .obj/release-shared/qregexp.o .obj/release-shared/qshareddata.o .obj/release-shared/qsize.o .obj/release-shared/qstring.o .obj/release-shared/qstringlist.o .obj/release-shared/qtimeline.o .obj/release-shared/qvector.o .obj/release-shared/qvsnprintf.o .obj/release-shared/qabstractfileengine.o .obj/release-shared/qbuffer.o .obj/release-shared/qdatastream.o .obj/release-shared/qdebug.o .obj/release-shared/qdir.o .obj/release-shared/qdiriterator.o .obj/release-shared/qfile.o .obj/release-shared/qfileinfo.o .obj/release-shared/qiodevice.o .obj/release-shared/qprocess.o .obj/release-shared/qtextstream.o .obj/release-shared/qtemporaryfile.o .obj/release-shared/qresource.o .obj/release-shared/qresource_iterator.o .obj/release-shared/qurl.o .obj/release-shared/qsettings.o .obj/release-shared/qfsfileengine.o .obj/release-shared/qfsfileengine_iterator.o .obj/release-shared/qfilesystemwatcher.o .obj/release-shared/qfsfileengine_unix.o .obj/release-shared/qfsfileengine_iterator_unix.o .obj/release-shared/qprocess_unix.o .obj/release-shared/qfilesystemwatcher_inotify.o .obj/release-shared/qpluginloader.o .obj/release-shared/qfactoryloader.o .obj/release-shared/quuid.o .obj/release-shared/qlibrary.o .obj/release-shared/qlibrary_unix.o .obj/release-shared/qabstracteventdispatcher.o .obj/release-shared/qabstractitemmodel.o .obj/release-shared/qbasictimer.o .obj/release-shared/qeventloop.o .obj/release-shared/qcoreapplication.o .obj/release-shared/qcoreevent.o .obj/release-shared/qmetaobject.o .obj/release-shared/qmetatype.o .obj/release-shared/qmimedata.o .obj/release-shared/qobject.o .obj/release-shared/qobjectcleanuphandler.o .obj/release-shared/qsignalmapper.o .obj/release-shared/qsocketnotifier.o .obj/release-shared/qtimer.o .obj/release-shared/qtranslator.o .obj/release-shared/qvariant.o .obj/release-shared/qcoreglobaldata.o .obj/release-shared/qcrashhandler.o .obj/release-shared/qeventdispatcher_unix.o .obj/release-shared/qisciicodec.o .obj/release-shared/qlatincodec.o .obj/release-shared/qsimplecodec.o .obj/release-shared/qtextcodec.o .obj/release-shared/qtsciicodec.o .obj/release-shared/qutfcodec.o .obj/release-shared/qtextcodecplugin.o .obj/release-shared/qfontlaocodec.o .obj/release-shared/qiconvcodec.o .obj/release-shared/moc_qnamespace.o .obj/release-shared/moc_qthread.o .obj/release-shared/moc_qlocale.o .obj/release-shared/moc_qtimeline.o .obj/release-shared/moc_qfile.o .obj/release-shared/moc_qiodevice.o .obj/release-shared/moc_qtemporaryfile.o .obj/release-shared/moc_qsettings.o .obj/release-shared/moc_qfilesystemwatcher_p.o .obj/release-shared/moc_qfilesystemwatcher_inotify_p.o .obj/release-shared/moc_qpluginloader.o .obj/release-shared/moc_qlibrary.o .obj/release-shared/moc_qfactoryloader_p.o .obj/release-shared/moc_qabstracteventdispatcher.o .obj/release-shared/moc_qabstractitemmodel.o .obj/release-shared/moc_qeventloop.o .obj/release-shared/moc_qcoreapplication.o .obj/release-shared/moc_qmimedata.o .obj/release-shared/moc_qsocketnotifier.o .obj/release-shared/moc_qtimer.o .obj/release-shared/moc_qtranslator.o .obj/release-shared/moc_qobjectcleanuphandler.o .obj/release-shared/moc_qeventdispatcher_unix_p.o .obj/release-shared/moc_qtextcodecplugin.o -L/usr/lib64 -L/var/tmp/portage/x11-libs/qt-4.3.0/work/qt-x11-opensource-src-4.3.0/lib -lz -lm -lrt -lpthread -ldl /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: .obj/release-shared/qiodevice.o: relocation R_X86_64_PC32 against `QList<QByteArray>::clear()' can not be used when making a shared object; recompile with -fPIC /usr/lib/gcc/x86_64-pc-linux-gnu/4.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: final link failed: Bad value collect2: ld returned 1 exit status make[1]: *** [../../lib/libQtCore.so.4.3.0] Error 1 make[1]: Leaving directory `/var/tmp/portage/x11-libs/qt-4.3.0/work/qt-x11-opensource-src-4.3.0/src/corelib' make: *** [sub-corelib-all-ordered] Error 2
