共享库。C++ 与 Python

问：

为什么我会遇到分段错误。

我想因为我使用的是字符串，但是我可以解决这个问题吗？

简单的代码，例如

#include <iostream>
#include <string>
struct Person {
    int age;
    std::string firstName;
    std::string lastName;
    std::string phoneNumber;
};
extern "C" {
    Person* getPerson() {
        Person person = Person();
        person.age = 25;
        person.firstName = "John";
        person.lastName = "Doe";
        person.phoneNumber = "123456789";
        return new Person(person);
    }
    void deletePerson(Person* person) {
        delete person;
    }
}

from ctypes import cdll, Structure, c_char_p, c_int
person_lib = cdll.LoadLibrary('./lib.so')
class Person(Structure):
    _fields_ = [
        ('age', c_int),
        ('firstName', c_char_p),
        ('lastName', c_char_p),
        ('phoneNumber', c_char_p)
    ]
person_lib.getPerson.restype = Person
person_lib.deletePerson.argtypes = [Person]
person = person_lib.getPerson()
info = f"Name: {person.firstName} {person.lastName}\nAge: {person.age}\nPhone: {person.phoneNumber}"
print(info)
person_lib.deletePerson(person)

希望从 c++ 库中获取一些信息并在 python 中使用它
