exec_file crash on Debug mode (Win 10)

未指定任何仓库文件或测试。先在所述的 Windows 10、VS2019、VC142、Python 3.10 调试环境中重现崩溃，然后比较使用 PyRun_File 的失败 exec_file 路径与正常工作的 PyRun_SimpleFile 和 _Py_fopen_obj 路径。完成标准是在调试模式下执行 embedding.py，且不再出现报告中的崩溃。

I face a crash on build 1.78 of boost python, on Windows 10, VS2019, VC142, Python 3.10 only on debug mode. Here is the script

#ifdef _DEBUG

#undef _DEBUG

#endif
#define PY_SSIZE_T_CLEAN
#include <Python.h>
int main(int argc, char* argv[])
{
	Py_Initialize();
	char* f = const_cast<char*>("E:\\Projects\\TestBoostPython\\embedding.py");
	PyObject* fo = Py_BuildValue("s", f);
	PyObject* fb = Py_None;
	PyUnicode_FSConverter(fo, &fb);
	char* f_as_uft = PyBytes_AsString(fb);
	FILE* fs = fopen(f_as_uft, "r+");
	Py_DECREF(fo);
	Py_DECREF(fb);
	PyObject* result = PyRun_File(fs,
		f,
		Py_file_input,
		nullptr, nullptr);
	fclose(fs);
	Py_FinalizeEx();
	return 0;
}

which is exactly the exec_file of boost python.

However the following code runs smoothly on the same environment

#ifdef _DEBUG
#undef _DEBUG
#endif

#define PY_SSIZE_T_CLEAN
#include <Python.h>

int main(int argc, char* argv[])
{
	Py_Initialize();
	char* f = const_cast<char*>("E:\\Projects\\TestBoostPython\\embedding.py");
	PyObject* obj = Py_BuildValue("s", f);
	FILE* file = _Py_fopen_obj(obj, "r+");
	if (file != NULL) {
		PyRun_SimpleFile(file, f);
	}
	Py_Finalize();
}
