Note the tdes8-> Expand method.

Writing todayProgramThe Dynamic Buffer cbufflat is used. After reading data, tdes8's expand () method is used to change tdes8 to tdes16. Of course, the program reports an error and the simulator exits directly, obviously, the program has a serious error. After practice, it is found that expand does not implement 8-bit to 16-bit conversion by extending the memory area, but uses the existing Descriptor Memory area size, but only merges the memory, two 8 into a 16, if the information in the 8-bit descriptor exceeds the maximum length of half, the conversion fails. The expand method may fail to be converted because the memory address is not an even number.

Record at once to prevent further errors. Please give us some advice.
