Info you should have provided in your first post
Building the development version doesn't come with any guarantees and the error could indeed be related. This issue also shows up in the stable version and most of the time it is time-out related and you can continue with the build.
Did you check the glibc-check-log file (as mentioned in my previous post)?
BTW: If this is your first LFS build my advise would be to start with the current stable version, it is bug free and works. This would make your life a little easier when something goes wrong.
Hope this helps.
