sizeof(&b)与VC++中的bug

int main()
{//2013/3/12
//sizeof(&b)在VC++6.0中为400，而在Devc++中则是4，&b的类型是int (*)[100]，明显是一个指针，应该是4  
	int b[100];
	int *c = &b;  //编译错误 cannot convert `int (*)[100]' to `int*' in initialization 
	int (*a)[100] = &b;
	
	printf("%d\n",sizeof(b));          //400 
	printf("%d\n",sizeof(&b));         //4 
	
	system("pause"); 
	return 0;
