是不是我的gentoo没装好？

装完gentoo，用valgrind测试代码有很多问题。
$ cat 1.c
int main()
{
  return 0;
}

$ gcc 1.c -o 1
$ valgrind -v --track-origins=yes --trace-children=yes --undef-value-errors=yes --leak-check=full --show-reachable=yes --log-file=debug.log ./1

很多错误信息：

OS系统是最新的，刚更新过：

emerge --info看看系统基本情况

我又试了一下，gcc升级到 gcc-4.3.3-r2，就会出现上面到问题
现在使用4.3.2-r3，是正常的
