いろいろと調べるとgccのバグのもよう。しかも修正済みなんですね。

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41153

以前なんかのバグでgcc 4.4に戻してからそのままにしてしまってた。gcc 4.5でコンパイルしてみる。

# gcc-config 4.5.3
* Switching native-compiler to x86_64-pc-linux-gnu-4.5.3 …
>>> Regenerating /etc/ld.so.cache…                                                                                [ ok ]

* If you intend to use the gcc from the new profile in an already
* running shell, please remember to do:

*   . /etc/profile

# . /etc/profile
# emerge -av firefox

(・・・ 中略 ・・・)

>>> Original instance of package unmerged safely.
* Updating desktop mime database …
* Updating icons cache …                                                                                        [ ok ]
>>> www-client/firefox-11.0 merged.

まあ出来ますわな。
