It was almost certain introduced by:
2005-07-06  Jeff Law  <law@redhat.com>

        * tree-ssa-dce.c (cfg_altered): New global.
        (tree_dce_init): Initialize cfg_altered.
        (remove_dead_stmt): If we remove an edge in the CFG, then set
        CFG_ALTERED.
        (perform_tree_ssa_dce): If we altered the CFG, then invalidate
        the dominators.
