                <SanjaByelkin> timour: it might be good idea to put DBUG_ASSERT(!is_cond_and(this) || !is_cond_or(this) || list.elements > 1)
                <SanjaByelkin> in Item_cond::fix_fields
                <timour> SanjaByelkin, also in quick_fix_fields - it is called often on synthetic Items (especially AND/OR)

                Oleksandr Byelkin,

                Is it applicable to 10.x?
                If yes, please update the Affects/Fix versions (and adjust priority if necessary); if it's 5.3-only bug, obviously it won't be fixed, please close it as "Won't fix" then.
                Thanks.
