(I build ports in a way that allows large load averages relative to the hardware-thread count. I also have a lot of swap configured.

Rebuilt. Reinstalled. Rebooted into the 13_0R-amd64 be area. Bulk build started. Bulk build completed. (Took longer because I let it run to completion.) No explicit reports of null characters.
