   @lanking520 The code you pointed out is correct, it disposes the NDArrays in the DataBatch created using the Slice operator. Slice operator does not create new NDArrays instead gives a reference to the original NDArray with an offset. The pointers to the NDArrays(both sliced and original) use shared_ptr which only decrements the reference count, so it won't free the original NDArray correspondingly if you don't dispose the Sliced NDArray it won't free the original even if the original NDArray is freed.
   
   I suspect the corruption to be elsewhere.
