The `SELECT col FROM t WHERE col NOT IN (col, ...) GROUP BY col' crashed in the range optimizer. The get_func_mm_tree function has been modified to check the Item_func_in::array field for the NULL value before using of that value. sql/opt_range.cc: Fixed bug #31075. The get_func_mm_tree function has been modified to check the Item_func_in::array field for the NULL value before using of that value. mysql-test/t/func_in.test: Added test case for bug #31075. mysql-test/r/func_in.result: Added test case for bug #31075.
