PyFunctionObject 在 Py_Finalize 中使程序崩溃，如果它在 PyTuple 中被设置了项目

我需要通过python文件获取函数名称和签名的列表。 Python 函数inspect.signature可以得到我的函数签名。 但是inspect.signature需要一个函数对象(PyFunctionObject(。inspect.getmembers可以返回这样的对象。 但是如果我在PyTuple中PyFunctionObject设置为项目，当执行Py_Finalize时 - 我得到错误。 另外，我正在使用Qt。

所以行PyTuple_SetItem(pFuncLink_arg, 0, pGetmember_tupleList);结果错误。

法典：。

PyObject *pName, *pModule;
PyObject *pInspect_module_name, *pInspect_module;
PyObject *pGetmember_function, *pGetmember_call_args, *pGetmembers_reply, *pGetsignature_function, *pGetmember_itemList, *pGetmember_tupleList;
PyObject *pFuncName, *pFuncLink_arg, *pFuncSign;
Py_Initialize();
QFileInfo fileInfo(QFile("X:/Projects/p-text.py"));
QString absPath = fileInfo.absolutePath();
QString fileName = fileInfo.baseName();
PyObject* sysPath = PySys_GetObject((char*)"path"); 
PyObject* programName = PyUnicode_FromString(absPath.toAscii());
PyList_Append(sysPath, programName);
pName = PyUnicode_FromString(fileName.toLatin1());
pModule = PyImport_Import(pName);
Py_DECREF(pName);
if (pModule != NULL){
pInspect_module_name = PyUnicode_DecodeFSDefault("inspect");
pInspect_module = PyImport_Import(pInspect_module_name);
pGetmember_function = PyObject_GetAttrString(pInspect_module, "getmembers");    
pGetsignature_function = PyObject_GetAttrString(pInspect_module, "signature");
pGetmember_call_args = PyTuple_New(1);
PyTuple_SetItem(pGetmember_call_args, 0, pModule);
pGetmembers_reply = PyObject_CallObject(pGetmember_function, pGetmember_call_args);
if (pGetmembers_reply){
Py_ssize_t const num_args = PyList_Size(pGetmembers_reply);
for (Py_ssize_t i = 0; i < num_args; ++i){
pGetmember_itemList = PyList_GetItem(pGetmembers_reply, i);
pGetmember_tupleList =  PyTuple_GetItem(pGetmember_itemList, 1);
if (PyFunction_Check(pGetmember_tupleList)){
pFuncName =  PyTuple_GetItem(pGetmember_itemList, 0);
QString funcName = PyObjectToString(pFuncName);
Py_DECREF(pFuncName);
pFuncLink_arg = PyTuple_New(1);
PyTuple_SetItem(pFuncLink_arg, 0, pGetmember_tupleList);
pFuncSign = PyObject_CallObject(pGetsignature_function, pFuncLink_arg);
if (pFuncSign == NULL) {
if (PyErr_Occurred()) {
PyErr_Print(); 
}
return;
}
QString funcSign = PyObjectToString(pFuncSign);
Py_DECREF(pFuncSign);
cout<<funcSign.toStdString()<<endl;
}
Py_DECREF(pGetmember_tupleList);
Py_DECREF(pGetmember_itemList);
}
}
Py_DECREF(pInspect_module_name);
Py_DECREF(pInspect_module);
Py_DECREF(pGetmember_function);
Py_DECREF(pGetsignature_function);
Py_DECREF(pGetmember_call_args);
}
else {
PyErr_Print();
}
Py_Finalize();

Py_Finalize()引发错误 "project_name.exe触发了断点">
