c++ - “__empty_global_delete”是什么意思

Question

该命令用于Visual Studio 2019的反汇编。

调用函数时出现“__empty_global_delete”。这是什么意思？

private:
    int A_num;
    int A_sum;
public:
    void fun1() { printf("fun1\n"); }
};

class B : public A {
private:
    int B_num;
    int B_sum;
public:
    void fun2() { printf("fun1\n"); }
};

void fun3() {
    printf("fun3\n");
}

int main(void) {
    B b;
    b.fun1();
    b.fun2();
    fun3();

    return 0;
}
