Bug #11766094 - 59132: MIN() AND MAX() REMOVE UNSIGNEDNESS
In the string context the MIN() and MAX() functions don't take
into account the unsignedness of the UNSIGNED BIGINT argument
column.
I.e.:
CREATE TABLE t1 (a BIGINT UNSIGNED);
INSERT INTO t1 VALUES (18446668621106209655);
SELECT CONCAT(MAX(a)) FROM t1;
returns -75452603341961.

Bug #11766094 - 59132: MIN() AND MAX() REMOVE UNSIGNEDNESS
The Item_cache_int::val_str() method has been modified to
take into account the unsigned_flag value when converting
data to string.
