] Huh? delete[]dp; is the last reference to dp. delete[]dots; is the last
] reference to dots. Whats the problem?

dp is modified so doesn't point to the base of the allocated area by the
time delete[] dp is called.  A separate working variable should be used
rather than modifying the allocation pointer.
