指针释放的问题

[cmkyec]

	double*** hist;
	int d = 4,n = 4;

	hist = (double***)calloc(d,sizeof(double**));
	for (int i = 0;i < d;i++)
	{
		hist[i] = (double**)calloc(d,sizeof(double*));
		for (int j = 0;j < n;j++)
		{
			hist[i][j] = (double*)calloc(n,sizeof(double));
		}
	}

	for (int i = 0;i < d;i++)
	{
		for (int j = 0;j < d;j++)
		{
			free(hist[i][j]);
		}
	}
	for (int i = 0;i < d;i++)
	{
		free(hist[i]);
	}
	free(hist);

如上的代码，当d >= n时，正常运行。但是当d < n时，释放时，便会报错。
在另外一台电脑上也是这个结果，为什么？

[就想叫yoko]

double*** hist;
int d = 4,n = 4;

hist = (double***)calloc(d,sizeof(double**));
for (int i = 0;i < d;i++)
{
	hist[i] = (double**)calloc(d,sizeof(double*));
	for (int j = 0;j < n;j++)
	{
		hist[i][j] = (double*)calloc(n,sizeof(double));
	}
}

for (int i = 0;i < d;i++)
{
	for (int j = 0;j < d;j++)//d改成n
	{
		free(hist[i][j]);
	}
}
for (int i = 0;i < d;i++)
{
	free(hist[i]);
}
free(hist);

汗，是我申请的时候写错了，谢谢关注
