If buildworld fails at a different place every time then  you probably 
have bad memory*.  Try memtest86+, memtest86 or if you have multiple 
sticks, try using each one in turn on its own and see if you still get 
the failure.

(*) It might be some other hardware problem, but bad memory is probably 
the most frequent and hopefully easiest to diagnose.  Other 
possibilities include bad memory socket, or just bad seating.
