Hi Michele,
After add --disable-libsanitizer and --disable-libmpx to the configure step of 4.9, it passed, Thank you!
And I think these two options should be added to the document page of step 4.9.

Hi Andrew,
Thanks for you suggestions.
On step 4.7 (http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-static.html), I replaced GCC 6.2.0 by GCC 6.5.0,
And this time, step 4.7 passed, then step 4.8 (http://clfs.org/view/clfs-embedded/x86/cross-tools/libc.html) also passed,
But on step 4.9 (http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-final.html), the error below occurred, could you give me suggestion again? Thanks.

I see that you're trying to compile also the c++ compiler. You have to add --disable-libsanitizer and --disable-libmpx to the configure step, it will fail otherwise

Newer versions of GCC have different default settings for what is
considered an error or a warning as compared to older versions of GCC.
I believe that GCC releases from version 7 onwards will hit this issue
when building GCC 6.3.
I believe that newer releases of GCC version 6 (like version 6.4 or
6.5) should fix this. You could try using a newer version of GCC 6.
Or you can have a try at applying this patch from OpenEmbedded:
https://patchwork.openembedded.org/patch/138884/
Sorry, I don't have a better or more detailed answer for you right now.
Thanks,
Andrew
