    Description

      I'm testing the MDEV-10134 feature tree, branch bb-10.2-default.

      This script:

      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a INT DEFAULT b, b INT DEFAULT 4);
      		 
      INSERT INTO t1 VALUES (DEFAULT,5);
      		 
      SELECT * FROM t1;

      returns

      +-------------+------+
      		 
      | a           | b    |
      		 
      +-------------+------+
      		 
      | -1886417009 |    5 |
      		 
      +-------------+------+

      Looks wrong, most likely some non-initialized data gets written into the column "a".
