Hi,
I'm having trouble upgrading a system running 9-stable to a new
revision. buildworld always dies with an "internal compiler error"
during lib/clang/libllvminstcombine.
The machine is currently running:
FreeBSD fred 9.1-STABLE FreeBSD 9.1-STABLE #0 r251914: Tue Jun 18
20:30:07 BST 2013 root@fred:/usr/obj/usr/src/sys/FRED amd64
I'm trying to upgrade to svn stable/9 r256049.
I tried switching off compiler optimisations in make.conf but that
didn't work. The very same error happens since August, different revisions.
Bits from the script(1)-ed output are:

Any idea how to work around this? Or what to do about it?
Thanks!
