c++ - GCC 4.9.1 在 RHEL 6.0 上编译失败，编译错误在 "libsanitizer"

Question

谁能帮我理解这里出了什么问题 -

这个错误是在我制作 gcc 4.9.1 时出现的。

最近的谷歌搜索显示:

但即使他面临完全相同的问题，也没有解决方案。

我在 CentOS 6.0 上遇到了同样的问题:在尝试编译 GCC-4.9.3 时，我遇到了同样的错误。

我能够使用以下解决方法:在配置 GCC 时禁用 libsanitizer 和 libcilkrts:

./configure --prefix=/home/gz/apps/gcc-4.9.3 --enable-languages=c,c++ \
    --disable-multilib --disable-libsanitizer --disable-libcilkrts
