Has anyone else seen a crash in base/head in abd_put() after r320156?

One of my experimental VMs at home crashed spectacularly after 
upgrading to r320156. I even wiped my /usr/obj, recompiled everything 
and got the same result. Everything's back to normal when I boot 
r320146.

Here's the backtrace:
