exec_file crash on Debug mode (Win 10)

No repository files or tests are named. Reproduce the crash on the stated Windows 10, VS2019, VC142, Python 3.10 debug setup, then compare the failing exec_file path using PyRun_File with the working PyRun_SimpleFile and _Py_fopen_obj path. Done means executing embedding.py in debug mode without the reported crash.

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();
}
