Fixed by r202944:

   2013-09-26  Richard Biener  <rguenther@suse.de>

        * tree-ssa-live.c (var_map_base_init): Handle SSA names with
        DECL_IGNORED_P base VAR_DECLs like anonymous SSA names.
        (loe_visit_block): Use gcc_checking_assert.
        * tree-ssa-coalesce.c (create_outofssa_var_map): Use
        gimple_assign_ssa_name_copy_p.
        (gimple_can_coalesce_p): Adjust according to the var_map_base_init
        change.

        * gcc.dg/tree-ssa/coalesce-2.c: New testcase.
