Destroy this allocator. In verbose mode, print all contained state values of this allocator object to stdout. Except in quiet mode, automatically report any memory leaks to stdout. Abort if either numBlocksInUse or numBytesInUse return non‐zero unless in no‐abort mode or quiet mode. Note that, in all cases, destroying this object has no effect on outstanding memory blocks allocated from this test allocator (and may result in memory leaks ‐‐ e.g., if the (default) MallocFreeAllocator singleton was used).
