Yes, I've seen exactly the same on other, earlier builds (I've been
using essentially exactly the same make.conf settings as what you just
posted, as well as using "make -j8").  That other error output I posted
earlier in this thread resulted after I had already seen the above, and
tried another buildworld without -j8.

So, apparently, the thing to do for now is *not* attempt to build a
debug world, it would seem.  I suspected as much.  :-)

Thank you very much for giving your attention to this matter.
