mysql8.0 upgrade crashes

I'm trying to upgrade my fbsd 13.1 system from MySQL 5.7 to 8.0. So I
shut down 5.7 cleanly, install the 8.0 package, start if up, and it
consistently crashes somwehere in the upgrade process. I don't think
there is anything very odd about my setup other than perhaps I set it
to put each innodb database in a separate directory.

I realize I could dump everything, install 8.0 from scratch, and
restore it all, but I have a lot of databases and that would be
painful so it would be really nice if I could get the upgrade to work.

R's,
John

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.
