netbsd-6 CVS branch amd64 build fails with gcc internal error

["J. Lewis Muir" <jlmuir%imca-cat.org@localhost>]

Hello, NetBSD Users.

I tried to build the netbsd-6 CVS branch (i.e. stable branch) from
source for amd64 on a NetBSD 6.1.4 amd64 machine using the BUILD-NetBSD
program from the sysutils/etcmanage 0.8.2 package, but the build
fails partway through with the message, "x86_64--netbsd-gcc: Internal
error: Killed (program cc1 received signal 9)". :-(

The console output for the beginning and end (after "[snip]") of the
build is below.  Right near the top is the actual build.sh command that
was run.

The machine is a VMware virtual machine.  I checked available disk
space, and that seems fine.  The machine has 256 MB of memory; I assume
that's fine.  The build is running with '-j2'; I assume that's fine,
but I could try no parallelism if that might help, but I'd be surprised
since I assume most everyone builds with parallelism.

I updated the CVS branch source just yesterday before building.

Does anyone know what's wrong and how to fix it?

Thank you!

Lewis
