my python script was blocked when my c++ encountered coredump

[zhangqiongyu]

my C++ code is:

#include <pybind11/pybind11.h>
#include <iostream>

int mydiv(int i, int j) {
    return i / j;
}

int seg(int i, int j) {
    int *invalid_ptr = reinterpret_cast<int *>(0xDEADBEEF);
    std::cout << "Triggering a segmentation fault by accessing an invalid memory location..." << std::endl;
    std::cout << "Value at 0xDEADBEEF: " << *invalid_ptr << std::endl;
    return i + j;
}

int ok(int i, int j) {
    int invalid_ptr = 123;
    std::cout << "Triggering a segmentation fault by accessing an invalid memory location..." << std::endl;
    std::cout << "Value at 0xDEADBEEF: " << invalid_ptr << std::endl;
    return invalid_ptr;
}

namespace py = pybind11;

PYBIND11_MODULE(example, m) {
    m.doc() = "pybind11 example plugin";

    m.def("mydiv", &mydiv, "A function which div two numbers",
          py::arg("i"), py::arg("j"));
    m.def("seg", &seg, "A function which seg",
          py::arg("i"), py::arg("j"));
    m.def("ok", &ok, "A function which ok",
          py::arg("i"), py::arg("j"));
}

My compile command is $ c++ -O3 -Wall -shared -std=c++11 -fPIC $(python3 -m pybind11 --includes) example.cpp -o example$(python3-config --extension-suffix)
And my python code is

import example
import signal
import faulthandler
import io



faulthandler.enable()
# faulthandler.register(signal.SIGFPE)

def handler(signum, frame):
    print('Signal SIGFPE handler called with signal', signum)
def handler1(signum, frame):
    print('Signal SIGSEGV handler called with signal', signum)
signal.signal(signal.SIGFPE, handler)
signal.signal(signal.SIGSEGV, handler1)

try:
    print("ok============")
    result = example.ok(1,2)
    print("seg============")

    # result = example.seg(1,2)
    # print("div============")

    result = example.mydiv(2, 0)
    print("aaa")

except RuntimeError  as e:
    print("aaabbb")

    print(str(e))
print(f"2 / 3 = {result}")

the python script is blocked when I use signal to capture the SIGFPE or SIGSEGV. So how can I solve this problem?Thx!!!!
