That is most likely a hardware problem.  Please run a full memtest,
and/or any other hardware diagnostics you can find.

It could also be running out of memory, but that is less likely, and you
usually get another signal then.  But who knows what might happen if you
choke a compiler. :)

It dies on exactly the same file?

You can't do that, you must run buildworld.

Yes, this is expected.  When you do not use the buildworld target, the
tblgen used above will be run from /usr/bin, which is too old.  This is
why buildworld first builds an up-to-date tblgen under /usr/obj, and
uses that to generate the needed files.
