New submission from Christian Berger:
I've been messing with PyGILState_... handling for my embedded python
interpreter and came across this issue:
code in PyGILState_Release:
PyThreadState *tcur = (PyThreadState *)PyThread_get_key_value(
autoTLSkey);
if (tcur == NULL)
Py_FatalError("auto-releasing thread-state, "
"but no thread-state for this thread");
The Py_FatalError() call will then invoke PyErr_Fetch() which won't check if
PyThreadState_GET() returns a valid ptr (!= NULL):
PyErr_Fetch(PyObject **p_type, PyObject **p_value, PyObject **p_traceback)
{
PyThreadState *tstate = PyThreadState_GET();
*p_type = tstate->curexc_type;
