This bug appears in both j602 and j701 (in both 32 bit and 64 bit
versions). I have only tested windows implementations but this result
should be platform independent:
1 (]@(p:@]_ _) -: ] . p:@]) 1

According to http://www.jsoftware.com/help/dictionary/d300.htm this
result should be true.
In other words:
1 ]@(p:@]_) 1

(good)
1 ] . p:@] 1
1
(bad)
A workaround is to not use dyadic verbs generated by the . primitive
but instead use
dot=:2 :0
u .v
:
u@(v(0 1 _ + v b. 0))
)
