PyNew_Interpreter(): "Fatal Python error, invalid thread state for this thread" question

[vincent wehren]

Hi,

Trying to grasp Py_NewInterpreter()in a simple app embedding Python, I was
wondering why the following gives me an error:

int main() {

    PyThreadState *tstate;

    Py_Initialize();
    //The following returns
    //Fatal Python error, invalid thread state for this thread
    tstate = Py_NewInterpreter();

   //etc..

Python is 2.3.3c1 on Win XP


Pointers much appreciated

Regards
