구조체를 malloc 할때 멤버의 메모리 주소가 겹칩니다

typedef struct ListCoreHeader
{
	int length;
	struct ListCore *head;
	struct ListCore *tail;
}ListCoreHeader;
 
typedef struct Solution_List	
{	
	ListCoreHeader Gene[8];		
} Solution_List;
 
typedef struct Solution_Matrix
{
	int tasknum;
	int core;
	int order;
} Matrix;
 
List = (Solution_List*)malloc(sizeof(Solution_List)*300);
 
Matrix = (Solution_Matrix**)malloc(sizeof(Solution_Matrix*)*300);
for ( i=0 ; i<300 ; i++ ) {
	Matrix[i] = (Solution_Matrix*)malloc(sizeof(Solution_Matrix)*1000);			
}
