If I empty out /usr/obj, then the build works, but takes a few hours. If I do a no-clean build with /obj/obj populated with he contents of a previous build, and /usr/src with updated ("svn update") sources, then the below nearly always happens early in the rebuild. It is in "stage 4.4: building everything" that this happens. The build is parallel (-j8), and I have manually de-threaded the output.

Hi

I got the same on amd64 with a meta mode build, on zfs as well. Oddly
(or not), it happens only if I make buildworld as a normal user, but
not as root. A second make buildworld always succeed.
