The patch that breaks this is:
2003-09-13 Diego Novillo <dnovillo@redhat.com>
* tree-flow-inline.h (is_optimizable_addr_expr): Remove. Update
all users.
* tree-ssa-dom.c (optimize_stmt): Do not propagate SSA names from
redundant expressions across abnormal edges.
The problem is in the removal of is_optimizable_addr_expr, the second part does
not cause the problem.
