sdac 7.2.9, delphi 10.
irreproducible, but again and again at customer:

(000107F5){} [038C17F5] System.@Assert
(000E4E7D){} [049C5E7D] MemData.TStringHeap.AddRef
(000DBAEB){} [049BCAEB] MemData.TData.AddRefComplexFields

(00427C01){} [03CD8C01] Data.DB.TDataSet.CheckBrowseMode
(0042694D){} [03CD794D] Data.DB.TDataSet.MoveBy

Do you have an idea? Our bug/your bug? solved perhaps in newer sdac? some explanation/way to analyze & correct?

Thanks very much for some tips, Ludek.

(I don't want to begin with just newer sdac, because i'm very afraid it will not help and introduce new more drastic bugs, till I now, it really helps...)
