为啥调用$Break()$后仍能访问Data[99]

#include<cstdio>
#include<cstring>
#include<algorithm>
using namespace std;

template<typename Datas>
struct Aker{
	Datas *Data;
	inline void Init(){
		Data=new Datas [100];
		
	}
	inline void Break(){
		delete [] Data;
	}
	inline void Printf(){
		printf("%d\n",Data[99]);
	}
};Aker<int>G;
int main(){
	G.Init();
	
	G.Data[99]=10;
	
	G.Printf();
	
	G.Break();
	
	G.Printf();
}
