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.
