Look at bashhist.c:maybe_append_history(). If bash doesn't think there have been any new history entries during the current session (history_lines_this_session must be > 0), or if those entries aren't past where we are in the history (history_lines_this_session must be < where_history()), it won't write anything to the history file. If you want to debug it, that's where I'd start.
