Why does the Python/C API crash on PyRun_SimpleFile?

Question

I\'ve been experimenting with embedding different scripting languages in a C++ application, currently I\'m trying Stackless Python 3.1. I\'ve tried several tutorials and exa

The below code will execute the test.py module. Python will search the module in the path set. So the path should be handled first.

Py_Initialize();

string path = "Python Scripts/";

//Set the path
PyRun_SimpleString("import sys");
string str = "sys.path.append('" + path + "')";
PyRun_SimpleString(str.c_str());

//Dont use test.py as it actually searches sub module test>>py
PyObject * moduleName = PyUnicode_FromString("test");
PyObject * pluginModule = PyImport_Import(moduleName);

if (pluginModule == nullptr)
{
    PyErr_Print();
    return "";
}

//Do the executions here

//clean up
Py_DECREF(moduleName);
Py_DECREF(pluginModule);
Py_DECREF(transformFunc);
Py_DECREF(result);

Py_Finalize();
