Jason, the call chain here is set_up_extended_ref_temp -> get_target_expr ->
get_target_expr_sfinae -> build_target_expr_with_type ->
type_has_nontrivial_copy_init, which hits gcc_assert (COMPLETE_TYPE_P (t)).

Looks like tweaking, eg, build_target_expr_with_type, to check for the
offending situation and return error_mark_node avoids the ICE, but I don't know
at the moment if something deeper is actually going on...
