When updating my system, Mozilla 1.7.2-r1 fails to build with internal compiler error on C&P from build log (lines not pertaining to this source file left out): g++ -o nsGNOMERegistry.o -c -DOSTYPE=\"Linux2.6\" -DOSARCH=\"Linux\" -I. -I../../dist/include/xpcom -I../../dist/include/string -I../../dist/include/unicharutil -I../../dist/include/mimetype -I../../dist/include/uriloader -I../../dist/include/dom -I../../dist/include/necko -I../../dist/include/rdf -I../../dist/include/webshell -I../../dist/include/helperAppDlg -I../../dist/include/plugin -I../../dist/include/pref -I../../dist/include/intl -I../../dist/include/uconv -I../../dist/include/windowwatcher -I../../dist/include/docshell -I../../dist/include/exthandler -I../../dist/include -I/var/tmp/portage/mozilla-1.7.2-r1/work/mozilla/dist/include/nspr -I/usr/X11R6/include -fPIC -I/usr/X11R6/include -fno-rtti -fno-exceptions -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wno-long-long -march=athlon -pipe -Wno-deprecated -fshort-wchar -pthread -pipe -DNDEBUG -DTRIMMED -ffunction-sections -O2 -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/X11R6/include -I/usr/include/atk-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/X11R6/include -DMOZILLA_CLIENT -include ../../mozilla-config.h -Wp,-MD,.deps/nsGNOMERegistry.pp ./unix/nsGNOMERegistry.cpp In file included from ../../dist/include/string/nsString.h:79, from unix/nsGNOMERegistry.cpp:42: ../../dist/include/string/nsTString.h:499: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

UPDATE: build completed successfully with MAKEOPTS="-j1" emerge mozilla so this can be seen as a workaround...
Please re-open if still an issue with 1.7.5. This version no longer in portage.
