      Not reproducible on 10.x.
      No obvious immediate problem on a non-debug build. EXPLAIN from the non-debug build, assuming it's the same (on a debug build EXPLAIN also fails):

      EXPLAIN EXTENDED SELECT DISTINCT l_orderkey FROM lineitem FORCE KEY (i_l_orderkey, i_l_receiptdate) WHERE l_orderkey > 1 ORDER BY l_receiptdate;

      Not reproducible on this test case with MyISAM or Aria, the plan is different there.

      The failure started happening after the selectivity merge into 11.0
