c++ - 我使用什么 C++ 编译器选项来触发数组越界错误？

Question

下面的代码中存在数组越界问题和缺失的 delete []。

使用以下选项编译代码不会触发任何错误:

g++ -std=c++2a -Wall -pedantic -fstack-protector-all test.cpp

#include <iostream>

class Base {
public:
    Base() { std::cout << "Base()\n";  }
    ~Base() { std::cout << "~Base()\n"; }
   int m_counter;
};


class Derived: public Base {
public:
    Derived() { std::cout << "Derived()\n"; }
    ~Derived() { std::cout << "~Derived()\n"; }
};


int main() {
    Base* b = new Derived[10];
    std::cout << b[10].m_counter << '\n';
    delete b;
    return 0;
}

关于我在这里可能遗漏了什么的任何指示？
