This indicates to me that you made an error in Chapter 5.  The error was 
probably in either gcc or glibc.

When we prepare for a LFS release, we have automated scripts that 
extract the instructions from the book and build the entire system. 
Your work around is not necessary if all the instructions are followed 
properly.

Your comment is that you "pretty much" followed the book.  Either you 
made purposeful changes or missed an instruction.   If you made *any* 
intentional deviations, please elaborate them.

In either case, I wouldn't trust your system.  I recommend starting 
over.  Of course, it's your distro, so you make the rules for your system.
