Sergey Glukhov a31795b82d Bug#40953 SELECT query throws "ERROR 1062 (23000): Duplicate entry..." error ...

Table could be marked dependent because it is
either 1) an inner table of an outer join, or 2) it is a part of
STRAIGHT_JOIN. In case of STRAIGHT_JOIN table->maybe_null should not
be assigned. The fix is to set st_table::maybe_null to 'true' only
for those tables which are used in outer join.
