I think you need to try this again on the 4.0 branch as 20050322 is getting old and this is most likely 
the same as PR 20249 which was fixed  on 2005-03-25 which is after the checkout you have.

I tried it on the mainline and I don't get the ICE so I really think this is a dup of bug 20249.
Can you try a newer compiler than what you have and this ICE is gone?

Hmm, maybe this is only reproducable on the 4.0 branch.
