I haven't seen any posts with problems.
I use x86 and haven't noticed any problems either, but I haven't used that
system much.
Check bugzilla.

Pasting the original announcement below.

Hello Hardened users, this is just a quick heads up.  GCC 4.3.4 will be
going
stable on hardened profiles shortly.  Unlike Hardened GCC 3.4.6, this
version
lacks default SSP building.  However, FORTIFY_SOURCE=2
and -fno-strict-overflow are now enabled by default.  Other Hardenedcompiler
features (ex. default relro, bind now & pic/pie building) remain enabled -
no
change from 3.4.6.

It is regretable this must be done before GCC4 is SSP-by-default enabled.
However, more and more packages require the newer GCC.  The stable GCC on
Hardened has been GCC 3.4.6 for a long time, but this has become an
untenable
situation.  GCC4 SSP-by-default works and will be added in a later revision
-
some GCC4+SSP bugs in grub and glibc also remain to be fixed.

Please follow '2. General Upgrade Instructions' in the 'Gentoo GCC Upgrade
Guide' [1] when upgrading from GCC 3.4.x to GCC 4.3.x.  The upgrade should
be
relatively smooth, but if you run into upgrade troubles seek help via this
mailing list, bugs.gentoo.org, or irc.freenode.net, #gentoo-hardened.
