New submission from 123 wlpha <[email protected]>:
PyGILState_Release does not really release gil, causing the next
PyGILState_Ensure deadlock, now you need to call if (PyGILState_Check () > 0)
{PyEval_SaveThread ();}
```
auto gil = PyGILState_Ensure();
// call c api
PyGILState_Release (gil);
if (PyGILState_Check () ＞ 0) {
PyEval_SaveThread ();
}
```
