Error 0xC0000005 when importing a module generated with Boost::Python

Question

I have the following benchmark.cpp file:

#include <boost/python.hpp>

char const* greet()
{
    return "hello, world";
}

BOOST_PYTHON_MODULE(benchmark)
{
    using namespace boost::python;
    def("greet", greet);
}

which is built using CMakeLists.txt containing i.a. the following pieces of code:

cmake_minimum_required(VERSION 3.21)

find_package (Python3 COMPONENTS Interpreter Development REQUIRED)
find_package(Boost COMPONENTS python REQUIRED)

set(BENCHMARK_MODULE benchmark)
add_library(${BENCHMARK_MODULE} MODULE benchmark.cpp)
set_target_properties(${BENCHMARK_MODULE} PROPERTIES PREFIX "" SUFFIX ".pyd")
target_include_directories(${BENCHMARK_MODULE} PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})
target_include_directories(${BENCHMARK_MODULE} PUBLIC ${Boost_INCLUDE_DIR})
target_include_directories(${BENCHMARK_MODULE} SYSTEM PUBLIC ${Python3_INCLUDE_DIRS})
target_link_libraries(${BENCHMARK_MODULE} PUBLIC ${Python3_LIBRARIES})
target_link_libraries(${BENCHMARK_MODULE} PUBLIC ${Boost_LIBRARIES})

I'm building on Windows 10 using MSYS2's MinGW64 and Ninja generator; using Python 3.12.

Dependencies - An open-source modern Dependency Walker gave me the following dependencies for benchmark.pyd:

• C:\WINDOWS\system32\kernel32.dll
• C:\msys64\mingw64\bin\libgcc_s_seh-1.dll
• C:\WINDOWS\system32\MSVCRT.dll
• C:\msys64\mingw64\bin\libstdc++-6.dll
• C:\msys64\mingw64\bin\libboost_python311-mt.dll
• C:\Program Files\Python312\python312.dll

so in Python code, I've tried to import that module in the following way:

import os
import sys

sys.path.append('C:\\msys64\\mingw64\\bin')
[os.add_dll_directory(path) for path in sys.path if os.path.isdir(path)]

import benchmark

but when I run this code, I get "Process finished with exit code -1073741819 (0xC0000005)" message when importing benchmark module.

What is the reason for such behavior? How to fix it?
