    Fixed LP bug #887496. · b2e5a3f6
    Igor Babaev authored
    This bug in the function Loose_scan_opt::check_ref_access_part1 could lead
    to choosing an invalid execution plan employing a loose scan access to a
    semi-join table even in the cases when such access could not be used at all.
    This could result in wrong answers for some queries with IN subqueries.
