I am wondering if you mean 10.0.2 here? (Since GTID was not included in
10.0.1, only 10.0.2).

There was a change to rpl.rpl_gtid_crash.test to use --append_file instead of
--remove_file/--write_file. Though these failures look like something else...

I can't think of anything else right now, but if you send the files then there
is a good chance I can say more.
