      Reproducible on 10.3-10.5.
      Debug and non-debug builds crash the same way.

      Also happens with

      VALUES ( DEFAULT );
      

      Note, on the contrary, these two statements return an error without crashing:

      EXECUTE IMMEDIATE 'VALUES (?)' USING IGNORE;
      EXECUTE IMMEDIATE 'VALUES (?)' USING DEFAULT;
      

      ERROR 4032 (HY000): Default/ignore value is not supported for such parameter usage
