buildworld fails with "Zero byte read from file, skipping rest of line"

[Jeremie Le Hen]

Hi,

I have a FreeBSD -CURRENT in Virtualbox (running on Linux).  I have been
unable to buildworld for a while.

I suspect this is not a problem with the source because I didn't see any
report so far, whereas I've been experiencing this for a month or more.
Thus I naturally suspected it was a binary problem, so I've upgraded
to the latest snapshot, but the problem still exists.

  ===> gnu/usr.bin/groff/src/libs/libgroff (all)
  make[6]: "/usr/obj/usr/src.svn/tmp/usr/src.svn/gnu/usr.bin/groff/src/libs/libgroff/.depend" line 3: warning: Zero byte read from file, skipping rest of line.

Any ideas?
