Shorter SQL scripts reproducing the same problem:

CREATE OR REPLACE TABLE t1 (a VARCHAR(128));
 
INSERT INTO t1 VALUES ('1e310');
 
INSERT INTO t1 VALUES ('-1e310');
 
INSERT INTO t1 VALUES ('0');
 
SELECT STDDEV_SAMP(a) FROM t1;


CREATE OR REPLACE TABLE t1 (a DOUBLE);
 
INSERT INTO t1 VALUES (1.7e+308), (-1.7e+308), (0);
 
SELECT STDDEV_SAMP(a) FROM t1;

Repeatable with MySQL-5.7 and MySQL-8.0.
