I got a crash on Windows in Objects/genobject.c:
void
_PyGen_Finalize(PyObject *self)
{
PyGenObject *gen = (PyGenObject *)self;
PyObject *res = NULL;
PyObject *error_type, *error_value, *error_traceback;
if (gen->gi_xframe == NULL || _PyFrameHasCompleted(gen->gi_xframe)) {
<------- Crash is here
/* Generator isn't paused, so no need to close */
return;
}
...
It looks like gen->gi_xframe is a junk-but-not-NULL pointer that is getting
dereferenced by _PyFrameHasCompleted.
Maybe related to bpo-44590.
