I have been seeing inconsistent results from the dyad 22 b.&.(a.&i.)
I do not have a repeatable test - the variations seem to be path dependent (same data gives different results depending on how the data was generated). However, replacing the above dyad with a more verbose alternative apparently prevented the inconsistencies from occurring. This smells like buggy special code but it might be some external dependence (perhaps an uninitialized value?) Unfortunately, I do not currently have any good ideas for isolating this problem.
