The two zeroes are initializers for locals which were edited out at the
last minute -- make sure you have:

...
: TEST          0 LOCALS| lowraddr |    \ <?> TEST #<name># --> <?>
...

I got the following for V6.10.4 ...

    V6.11.09  V6.10.04

w1      1       2
w2     77       78
w3     97       83
w4     11       11
