New submission from Terry Cooper: The Python statement gList1[i1][1] += gList2[i2][1] modifies not only gList1 (a volatile storage object) but dBasis[163] (a record within shelve object dBasis). Both gList and dBasis[163] are printed before and after execution of the statement by cFract2.combine. They are obviously not the same record, but the statement modifies gList1[2][1] and dBasis[163][2][1] simultaniously.
