Segmentation Fault when Using PyArray_SimpleNewFromData

Similar kind of questions have been asked by other users but none of the answers work for me. Here is my code, which is inspired by https://ubuntuforums.org/showthread.php?t=1266059

#include <stdio.h>
#include <Python.h>
#include "numpy/arrayobject.h"

int main() {
    printf("Embedding Python\n");
    PyObject *pName, *pModule, *pFunc;
    PyObject *pArgs, *pValue, *vec;

    const char* script = "TestScript";
    const char* function = "Test";

    Py_Initialize();

    pName = PyUnicode_FromString(script);
    pModule = PyImport_Import(pName);

    if (pModule != NULL) {
        printf("Step-1\n");

        pFunc = PyObject_GetAttrString(pModule, function);

        fflush( stdout );
        printf("Step-2\n");

        if (pFunc && PyCallable_Check(pFunc)) {
            // define a vector
            double* v = new double[3];
            v[0] = 1.0;
            v[1] = 2.0;
            v[2] = 3.0;             

            fflush( stdout );
            printf("Step-3\n");

            npy_intp vdim[] = { 3 };

            fflush( stdout );
            printf("Step-4\n");

            vec = PyArray_SimpleNewFromData(1, vdim, PyArray_DOUBLE, (void*)v);

            fflush( stdout );
            printf("Step-5");

            pArgs = PyTuple_New(2);
            PyTuple_SetItem(pArgs, 0, vec);
            PyTuple_SetItem(pArgs, 1, vec);

            pValue = PyObject_CallObject(pFunc, pArgs);
            Py_DECREF(pArgs);
            Py_DECREF(pName);

            if (pValue != NULL) {
                printf("Result of call: %f\n", PyFloat_AsDouble(pValue));
                Py_DECREF(pValue);
            }

            delete [] v;
        } else {
            if (PyErr_Occurred()) {
                PyErr_Print();
                fprintf(stderr, "Cannot find function \"%s\"\n", function);
            }
        }
    } else {
        PyErr_Print();
        //fprintf(stderr, "Failed to load \"%s\"\n", argv[1]);
        return 1;
    }

    Py_Finalize();
    return 0;
}

I compile this code using Python3.5 on Ubuntu 16.04. Here is command to compile the code

On executing I get following output
