[issue23996] _PyGen_FetchStopIterationValue() crashes on unnormalised exceptions

[Stefan Behnel]

Stefan Behnel added the comment:

I noticed that my patch isn't entirely correct. If the exception value is a tuple, both PyErr_SetObject() and PyErr_NormalizeException() use it directly as *argument tuple* for the exception instantiation call, i.e. they essentially unpack it into separate arguments. The StopIteration value is then only the first item of that tuple.

I wonder if it's worth repeating this, uhm, surprising special case in yet another place, or if we should just always instantiate the exception.
