I am replying to my own thread.
Doing a PyStackless_GetRunCount() shows that 0 tasklets are running and that
explains why the st.current is in that state.However, I'm not sure crashing the
whole application is the best way for PyStackless_GetCurrent() to behave.
Also, what contributed to my confusion was that from the
PyRun_Simplestring("print stackless.getcurrent()") the return value was 1.I
guess I will look further today to see why exactly that is so.

Hello! I'm new to the field and I was trying a simple stackless embedding test
and experienced problems.Here is the short source code to my test:
#include <stackless_api.h>
#include <windows.h>
int main(void)
{
PyInterpreterState* pys;
Py_Initialize();
PyRun_SimpleString("import stackless");
PyRun_SimpleString("print
stackless.runcount");
PyRun_SimpleString("print stackless.getcurrent()");
PyObject *task;
task=PyStackless_GetCurrent(); // <==== CRASH HERE
Py_DECREF(task);
return 1;
}
I am using MSVC 8 and an unmodified distribution of Python 2.7.1 Stackless
3.1b3 060516,
built with the same compiler.
The crash happens inside PyStackless_GetCurrent, which looks like this:
PyObject
*
PyStackless_GetCurrent(void)
{
PyThreadState *ts = PyThreadState_GET();
PyObject *t = (PyObject*)ts->st.current;
Py_INCREF(t);
return t;
}
The crash happens on Py_INCREF(t), because the thread state object returned by
PyThreadState_GET
doesn't seem to be properly initialized.
I'm probably missing something very basic, but any help is appreciated.
Cheers!
