Were the hardened patches dropped in Firefox 3 ? Firefox 2.0.0.18 (before the upgrade) did not have any text relocations. Reproducible: Always Steps to Reproduce: 1. emerge >=www-client/mozilla-firefox-3.0 2. As root (th search everywhere), scanelf -aq -lpR | grep TEXTREL 3. Watch the scanelf output Actual Results: 0755 LE TEXTREL $ORIGIN:$ORIGIN/..:/usr/lib/nspr /usr/lib/mozilla-firefox/components/libbrowserdirprovider.so 0755 LE TEXTREL $ORIGIN:$ORIGIN/..:/usr/lib/nspr /usr/lib/mozilla-firefox/components/libbrowsercomps.so 0755 LE TEXTREL $ORIGIN /usr/lib/mozilla-firefox/firefox 0755 LE TEXTREL $ORIGIN /usr/lib/mozilla-firefox/libjemalloc.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/libmozjs.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/xulrunner-bin 0755 LE TEXTREL $ORIGIN /usr/lib/xulrunner-1.9/xpidl 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/sdk/lib/libmozjs.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nss:/usr/lib/nspr /usr/lib/xulrunner-1.9/sdk/lib/libxul.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/sdk/lib/libxpcom.so 0755 LE TEXTREL $ORIGIN:$ORIGIN/..:/usr/lib/nspr /usr/lib/xulrunner-1.9/components/libxpctools.so 0755 LE TEXTREL $ORIGIN:$ORIGIN/..:/usr/lib/nspr /usr/lib/xulrunner-1.9/components/libimgicon.so 0755 LE TEXTREL $ORIGIN /usr/lib/xulrunner-1.9/xulrunner-stub 0755 LE TEXTREL $ORIGIN /usr/lib/xulrunner-1.9/libjemalloc.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nss:/usr/lib/nspr /usr/lib/xulrunner-1.9/libxul.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/plugins/libnullplugin.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/plugins/libunixprintplugin.so 0755 LE TEXTREL $ORIGIN:/usr/lib/nspr /usr/lib/xulrunner-1.9/libxpcom.so 0755 LE TEXTREL $ORIGIN /usr/lib/xulrunner-1.9/xpt_dump 0755 LE TEXTREL $ORIGIN /usr/lib/xulrunner-1.9/xpt_link Expected Results: No TEXTREL in scanelf output at least. Ideally, no output from scanelf (those annoying RPATHs)

Same problem here on hardened x86 (gcc 3.4.6). This seems to be related to the gcc visibility=hidden pragmas (that get included in every file through '-include $(top_srcdir)/config/gcc_hidden.h'. This pragma results in some non-PIC code even when built -fPIC. Patching configure.in to remove the whole -fvisibility=hidden check (i.e. making sure that HAVE_VISIBILITY_HIDDEN_ATTRIBUTE is not defined, and that no VISIBILITY_FLAGS are passed) before eautoreconf gives me a quick-and-dirty workaround, which builds firefox-3.0.5 without TEXTRELS. Some quick googling gave me this, which might be related : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=331460
Fixed properly by adding "-fno-stack-protector -fno-stack-protector-all" to CXXFLAGS, see bug #253639.
Fixed in cvs, wait an hour and emerge --sync. Thanks for reporting and testing.
