Re: [Cython] segfault in 'async def' coroutines

I've just discovered that same thing has to be fixed for
__name__.

Hi,

Under some circumstances, in asyncio code that runs in uvloop [1],
cython code segfaults in cython/Cython/Utility/Coroutine.c:


  static PyObject *
  __Pyx_Coroutine_get_qualname(__pyx_CoroutineObject *self)
  {
    Py_INCREF(self->gi_qualname);
    return self->gi_qualname;
  }


"self->gi_qualname" can be NULL.  The correct code is probably:


  __Pyx_Coroutine_get_qualname(__pyx_CoroutineObject *self)
  {
    if (self->gi_qualname == NULL) { return __pyx_empty_unicode; }
    Py_INCREF(self->gi_qualname);
    return self->gi_qualname;
  }


Thanks,
Yury
