error C2541: 'delete' : cannot delete objects that are not pointers

Возникает сабж при попытке компиляции в Visual C++ 2008.

Вот сама функция, в которой вылезают ошибки:

void clearResult(ResultData &rez, InputData &inp)
{
	rez.exist = false;
	rez.min = 0;
	rez.minln = 0;
	
	if (rez.arrival != NULL)
		for (int i=0; i<inp.k; i++)
			for (int j=0; j<inp.k; j++)
				delete [] rez.arrival[i][j]; //error C2541: 'delete' : cannot delete objects that are not pointers
	
	delete [] rez.arrival;
	rez.arrival = NULL;

	if (rez.costs != NULL)
		for (int i=0; i<inp.k; i++)
			for (int j=0; j<inp.k; j++)
				delete [] rez.costs[i][j]; //error C2541: 'delete' : cannot delete objects that are not pointers

	delete [] rez.costs;
	rez.costs = NULL;

	if (rez.sumcosts != NULL)
		for (int i=0; i<inp.k; i++)
			delete [] rez.sumcosts[i]; //error C2541: 'delete' : cannot delete objects that are not pointers

	delete [] rez.sumcosts;
	rez.sumcosts = NULL;

	return;
}

почему так? ведь данные же передаются в функцию по ссылке..
да и строчки вида delete [] rez.arrival; не вызывают ошибки..

уважаемые гуру, помогите, пожалуйста, разобраться!

вот кусок из хэдера

	struct InputData
	{
		int n, k, b;
		int** chargesMatrix;
		bool exist;

		InputData(){
			n = 0;
			k = 0;
			b = 0;
			exist = false;
			chargesMatrix = NULL;
		}
		
		~InputData(){
		}
	};

	struct ResultData
	{
		int** costs;
		int** arrival;
		int* sumcosts;
		int min, minln;
		bool exist;
		
		ResultData()
		{
		exist = false;
		min = -1;
		minln = -1;
		costs = NULL;
		arrival = NULL;
		sumcosts = NULL;
		}
		~ResultData()
		{

		}
	};


	extern InputData inpData;
	extern ResultData rezData, rezDataEureka;

				delete [] rez.costs[i];

	delete [] rez.costs;
	rez.costs = NULL;

	delete [] rez.sumcosts;
	rez.sumcosts = NULL;

	return;
}
