The compile bug has been fixed for me.  However, last I checked I can
still freeze a system by generating a lot of network traffic between VMs
in either bhyve or virtbox.  Its been a while since I tested (couple of
months) but I dont recall anything obviously committed that highlighted
that issue.  Note this is on Epyc and Ryzen boxes
