I am building a fresh LFS with the latest glibc and binutils and ran

What the error looks like is somewhat complex and it looks like (long
lines so there is wrapping in the email):

The command line includes -Werror even if I specify --disable-werror in
configure.
I've been able to work around the problem with:
sed -e '1161 s|^|//|' \
-i libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc
and it is probably all right since it is just an internal assertion check.

It's curious because I didn't run into the problem with gcc-pass1.
The build is now progressing through Chapter 6 with all tests so it will
be a while before the build finished, but if anyone has a look at this
and sees something I missed, please let me know.
----------------
I needed the sed above in Chapter 6 gcc, but otherwise everything else
built without any needed build changes. I did a complete set of Chapter
6 tests and did not note any changes to what we currently have documented.
What is in the development book now will probably be very close to the
LFS 9.1 release. Package freeze is scheduled for Feb 15.
