I'm not sure where to post this type of questions, first time on this forum, sorry, posting here.

Recently I have upgraded mysql from 5.7 to 8.0 (OS: FreeBSD 12.2 release)

now some of the stored proc cause a server to crash:

This one works:
~~~ cat testsp ~~~
CREATE DEFINER=`root`@`localhost` PROCEDURE `testsp`()
declare pw_hash varchar(200);
set pw_hash = md5(rand());
~~~ end cat ~~~

while this one cause a crash:

~~~ cat testsp2 ~~~
CREATE DEFINER=`root`@`localhost` PROCEDURE `testsp`()
declare pw_hash varchar(200);
set pw_hash = md5(rand());

--- next line cause server to crash ---
select pw_hash;
~~~ end cat ~~~

here is the error log file report:

~~~ cat srv.err ~~~

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
Thread pointer: 0x85ccb7000
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
