      Not reproducible with MyISAM or InnoDB.

      Non-debug build doesn't crash, but it produces a questionable table contents which is returned by SELECT in the test case:

      SELECT * FROM t1;
      a
      1
      2
      1
      

      Since the INSERT .. SELECT doesn't fail, it's reasonable to expect 4 rows in the table.
