    BUG#877288: Wrong result with semijoin + materialization + multipart key · 213eaebe
    Sergey Petrunya authored
    - when create_ref_for_key() is constructing a ref access for
      a table that's inside a SJ-Materialization nest, it may not 
      use references to fields of tables that are unside the nest (because 
      these fields will not yet have values when ref access will be used)
      
      The check was performed in the first of create_ref_for_key's loops (the 
      one which counts how many key parts are usable) but not in the second
      (the one which actually fills the TABLE_REF structure).
