It's related to
a) the type of "name" (I assume it's an ansistring or unicodestring)
b) how you free the memory to which mytest points

If you use freemem or reallocmem, then you will get a memory leak because freemem/reallocmem do not finalize the memory before freeing it. You have to manually call finalize() on the records inside that memory block prior to freeing them via freemem/reallocmem. dispose on the other hand will finalize the freed memory automatically.
