Trouble building/upgrading 9-stable

[Johannes Totz]

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 at 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!
