  I've tried GfxFont.ii and the reduced test on Itanium-2 under RHEL
4.4 for today gcc (revision 129849).  There are no crashes anymore.
Everything looks fine.  Probably, latest Maxim Kuvyrkov's patches
fixed this.

  Richard, could you tell what gcc revision you tried.

I don't remember, but the ICEs vanished for me as well with at least
a snapshot from 20071016.

I've checked patch http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=129378 and
as Jakub I confirm too that the patch fixed the bug.

So it is really fixed.
