48d1178ad8 Make sure that INSERT INTO ... SELECT ... always uses an ephemeral 
intermediate table if the SELECT clause refers to the destination table,
even if the SELECT clause is compound or uses the destination table
in a subquery.  This fixes a long-standing bug that can cause an
infinite loop for some SQL statements. (CVS 4552)

78d1ef1a51 Add disabled test cases for ticket #2652. We will enable these test cases 
after #2652 is fixed.  The fix will be difficult and will probably take
a while.  On the other hand, correlated aggregate queries have never
worked in SQLite and the problem is just now coming to light, so it is
probably not a pressing issue. (CVS 4435)
