Not really, for me:

gcc version 4.6.3 (Gentoo 4.6.3 p1.10, pie-0.5.2)

Fails miserably on any situation, even the most bare (non
c++/wchar/nls/ipv6/rpc) configuration.
If it's the USE flags (pretty default), some gentoo patches to gcc or
what else i don't know, but i can't get past gcc-initial (this being the
current stable on the normal architectures).
Regards.
