    Bug #14409015 MEMORY LEAK WHEN REFERENCING OUTER FIELD IN HAVING · af3fdefc
    Sergey Glukhov authored
    When resolving outer fields, Item_field::fix_outer_fields()
    creates new Item_refs for each execution of a prepared statement, so
    these must be allocated in the runtime memroot. The memroot switching
    before resolving JOIN::having causes these to be allocated in the
    statement root, leaking memory for each PS execution.
