It is about the sql_mode when building the plan for a 'out-of-ranged' date:

A simplified case to reproduce it:

set time_zone='UTC';
create table t02(a timestamp key);
select * from t02 where a != "2038-1-19 3:14:45";

And the error stack:

I think it is a corner case(very rared scenario for 'out-of-ranged' date condition and MySQL treat it as a warning instead of error:

mysql> select * from t02 where a != "2038-1-19 3:14:45";
Empty set, 1 warning (0.00 sec)

mysql> show warnings;

I would treat it as 'minor' compatibility bug and we need to update the planner to fix it.
