Dorit, I think your guess is right.

The ICE already disappeared with the patch
http://gcc.gnu.org/ml/gcc-cvs/2005-05/msg01207.html

        * tree-ssa-forwprop.c (forward_propagate_addr_expr):
        See through ADDR_EXPR in finding place to propagate into.

But that only seems to paper over the problem. Backing this patch out
I get the ICE again. It really disappears with Keith's patch you mentioned:

http://gcc.gnu.org/ml/gcc-cvs/2005-05/msg01301.html

So I think we can close the PR as fixed then.
