/usr/bin/as: out of memory allocating 4194304 bytes after a total of 524288000 bytes

I update my local mirror of the SVN repo nightly, then use it to track
stable/8, stable/9, and head in the mornings -- both on my laptop & on
my local build machine.

While that usually "just works," head has been a bit more turbulent in
the last few days.

My last successful build of head is reflected in:

FreeBSD g1-227.catwhisker.org 10.0-CURRENT FreeBSD 10.0-CURRENT #537 234416M: Wed Apr 18 05:35:03 PDT 2012     root_at_g1-227.catwhisker.org:/usr/obj/usr/src/sys/CANARY  i386

(I note that I have not attempted to migrate to using clang/llvm
to perform the build.)

The update after 234416 was to 234454; the attempted buildworld failed:

This morning, after updating the repo & the head working copy to 234489,
I'm still seeing the same problem.  (And this is on both the laptop & the
build machine.)

So at this point, I suspect that something was built "successfully"
(perhaps as recently as Wednesday, 18 Apr) that doesn't actually
work quite right.

I have access to a machine at work that I had last updated to head
as of 234311 (15 Apr; also i386), so I should be able to grab files
from it, if appropriate.

But I could use a clue or two.

Thanks!

Peace,
david
