Embedding: Problem with CallObject

[James Turner]

Hello.

I'm just starting to play with embedding Python in C, and I'm getting a
huge headache from trying to figure out what's wrong with my code here:

--test.c--
#include <Python.h>

int main(int argc, char** argv)
{
    PyObject *str,*mod,*flist,*func,*args;
    Py_Initialize();
    str = PyString_FromString("anything");

    /*Import mod */
    mod = PyImport_Import(PyString_FromString("one") );

    flist = PyModule_GetDict(mod);
    func = PyDict_GetItemString(flist,PyString_FromString("out"));

    args = PyTuple_New(1);
    PyTuple_SetItem(args, 0,str);

    /* FAILS HERE!! */
    PyObject_CallObject(func,args);

    Py_XDECREF(flist);
    Py_XDECREF(func);
    Py_XDECREF(args);
    Py_XDECREF(mod);
    Py_XDECREF(str);

    Py_Finalize();
    return 0;
}

--one.py--
def out(str):
    print  "C says: %s" % str

--end code--

And, right where I've commented FAILS HERE!! in the C code, I get the
lovely:

Segmentation fault (core dumped)

I one.py is in the current directory, so I run it 

$env PYTHONPATH=. ./test

It imports the module fine, and I can successfully run out(str) if I
change it to out() and pass it NULL from C.  (Meaning call the func w/no
arguments and just print "Hello World" or something.)

After testing this with:

 if (PyErr_Occurred())PyErr_Print(); 

all over the C code, I'm pretty sure this is why it's failing:  I'm doing
something wrong with the way I'm passing it that tuple from C.

Hopefully someone more skilled can lend a hand!

Thanks, James

(PS) -- I am aware of CallMethod with the formatted string... I'm looking
for a solution that enables one.py to modify my C-made PyObjects.  My
code is based on learning from http://www.mcmillan-inc.com/embed.html
and referring to the official Python/C Api @ www.python.org.
