There is a known bug in libedit's history file reader that can cause this crash. libedit is a system component that lldb uses to do command-line editing and the like.
Try moving ~/.lldb-history to some other name, and then rerunning the REPL. If that works, can you attach that history file to the Radar you mentioned, so we can make sure this is the same history reading bug?
