Caused by

basic_block pred, basic_block phiblock)

if (TREE_CODE (def) == SSA_NAME)

picking up VN inserted expressions. I re-wrote this as part of
2012-09-24 Richard Guenther
* tree-ssa-pre.c (bitmap_find_leader, create_expression_by_pieces,
find_or_generate_expression): Remove dominating stmt argument.
(find_leader_in_sets, phi_translate_1, bitmap_find_leader,
create_component_ref_by_pieces_1, create_component_ref_by_pieces,
do_regular_insertion, do_partial_partial_insertion): Adjust.
(compute_avail): Do not set uids.
and that fixed it. I am going to try backporting that change in isolation.
