I&#39;ve been stuck on gcc-3.4.6 on my hardened profile system (currently:<br>
hardened/linux/amd64/10.0) for a very long time.  Now it looks like<br>
gcc-4.3.4 has been stabilized for hardened profiles.  Has anyone<br>
tested it?  This system is critical for me, so I&#39;ve got to be careful.<br>

</font></blockquote></div><br>Hello <span class="il">Hardened</span> users, this is just a quick heads up.  GCC 4.3.4 will be going<br>
stable on <span class="il">hardened</span> profiles shortly.  Unlike <span class="il">Hardened</span> GCC 3.4.6, this version<br>
lacks default SSP building.  However, FORTIFY_SOURCE=2<br>
and -fno-strict-overflow are now enabled by default.  Other <span class="il">Hardened</span> compiler<br>
features (ex. default relro, bind now &amp; pic/pie building) remain enabled - no<br>
change from 3.4.6.<br>
<br>
It is regretable this must be done before GCC4 is SSP-by-default enabled.<br>
However, more and more packages require the newer GCC.  The stable GCC on<br>
<span class="il">Hardened</span> has been GCC 3.4.6 for a long time, but this has become an untenable<br>
situation.  GCC4 SSP-by-default works and will be added in a later revision -<br>
some GCC4+SSP bugs in grub and glibc also remain to be fixed.<br>
<br>
Please follow &#39;2. General Upgrade Instructions&#39; in the &#39;<span class="il">Gentoo</span> GCC Upgrade<br>
Guide&#39; [1] when upgrading from GCC 3.4.x to GCC 4.3.x.  The upgrade should be<br>
relatively smooth, but if you run into upgrade troubles seek help via this<br>
mailing list, <a href="http://bugs.gentoo.org/" target="_blank">bugs.<span class="il">gentoo</span>.org</a>, or <a href="http://irc.freenode.net/" target="_blank">irc.freenode.net</a>, #<span class="il">gentoo</span>-<span class="il">hardened</span>.<br>
