The GIL is likely held by a different thread, then. _PyThreadState_Current will point to the state of this other thread. > It looks that _PyThreadState_Current can be NULL if the GIL is released. > In this case, _Py_DumpBacktrace() just do nothing.

I don't think so. gil_last_holder might also refer to a different thread. > I don't think that it will possible the acquire the GIL in > Py_FatalError() or in the fault handler. I agree.
