第二次运行的线程出现错误 < >我使用Windows中的线程将C++中的插件连接到Python脚本。在会话期间，该线程将被多次调用

问题:

第二次调用调用python脚本的工作线程时，会发生以下情况：

->.exe程序崩溃，代码为： 运行时错误！ 程序：xxx.exe。 此应用程序已请求运行时以异常方式终止它。有关更多信息，请联系应用程序的支持团队

：在XXX.EXE中0x735C41F的第一个机会异常：微软C++异常：CMASIDIAGART异常在内存位置0x06A9F840。 如果存在此异常的处理程序，则程序可以安全地继续

将我引向mlock.c的以下几行：

我在哪里没有正确处理异常

在调试过程中，我注意到最后一行的_endthread从未到达，我也不知道为什么。这是问题的根源吗

代码：

以下是工作线程的代码：

void py_embed (void*data){

char *argv[4]={"PythonPlugIn2","bridge","test_callsign","MAH543"};
int argc=4;

ofstream textfile3;
textfile3.open("FP_python_embed.txt");

PyObject *pName, *pModule, *pDict, *pFunc, *pArgs, *pValue;
PyThreadState *mainThreadState,*myThreadState,*tempState;
PyInterpreterState *mainInterpreterState;

//To inform the interpreter about paths to Python run-time libraries
Py_SetProgramName(argv[0]);

// Initialize the Python Interpreter
Py_Initialize();

// Initialize thread support
PyEval_InitThreads();

// Save a pointer to the main PyThreadState object
mainThreadState = PyThreadState_Get();

// Get a reference to the PyInterpreterState
mainInterpreterState = mainThreadState->interp;

// Create a thread state object for this thread
myThreadState = PyThreadState_New(mainInterpreterState);

// Release global lock
PyEval_ReleaseLock();

// Acquire global lock
PyEval_AcquireLock();

// Swap in my thread state
tempState = PyThreadState_Swap(myThreadState);

// Build the name object
pName = PyString_FromString(argv[1]);

// Load the module object
pModule = PyImport_Import(pName);

// pDict is a borrowed reference 
pDict = PyModule_GetDict(pModule);

// pFunc is also a borrowed reference 
pFunc = PyDict_GetItemString(pDict, argv[2]);

//Do the Python things
PyObject *pArgs2, *pValue2;
pArgs2=Py_BuildValue("(s)",argv[3]);
pValue2 = PyObject_CallObject(pFunc, pArgs2);
textfile3<<PyInt_AsLong(pValue2)<<endl<<" worked1";
textfile3.close();

// Clean up
Py_DECREF(pModule);
Py_DECREF(pName);

// Swap out the current thread
PyThreadState_Swap(tempState);

// Release global lock
PyEval_ReleaseLock();

// Clean up thread state
PyThreadState_Clear(myThreadState);
PyThreadState_Delete(myThreadState);

// Finish the Python Interpreter
Py_Finalize();

_endthread();
};

注：与此相关的问题2是。

请每次提问一个问题。您认为我应该将此问题一分为二吗？您自己已经将其一分为二了。我也面临着这个问题。第二次用Py_Initialize调用函数会出现错误，你能告诉我解决方案吗？我不能，因为这是多年前的事了，我不记得了。抱歉@AreebMuzaffar
