Non-debug build crashes in a similar way.
Not reproducible on 10.1.

Somewhat different test case with similar but not identical stack traces.

CREATE TABLE t1 (a INT) ENGINE=MyISAM;
 
INSERT INTO t1 VALUES (NULL),(0);
 
 
 
CREATE TEMPORARY TABLE tmp (b INT, c INT AS (b) PERSISTENT, KEY(c)) ENGINE=MyISAM;
 
INSERT tmp (b) SELECT a FROM t1;
 
INSERT INTO tmp (b) VALUES (NULL);
 
 
 
# Cleanup
 
DROP TABLE t1;
