Fix

Please try this alternative fix. It has much better looking bloatcheck:

function                                             old     new   delta
dump_unified_vec                                     435     457     +22
diff_main                                            855     860      +5
diffreg                                             1786    1781      -5
do_diff                                              428     416     -12
