<li>Fix two bugs, which when combined might result in incorrect
    query results.  Both bugs were harmless by themselves; only when
    they team up do they cause problems.  Ticket #3581.

newsitem {2009-Jan-14} {Version 3.6.9} {
  Internal stress testing revealed a corner case where the cost function 
  on the query optimizer might mislead the query optimizer into making a 
  poor indexing choice.  That choice could then tickle another bug in 
  the VDBE which might result in an incorrect query result.  This
  release fixes both problems.  The chances of actually hitting this
  combination of problems in a real application seems remote.
  Nevertheless upgrading is recommended.
