+  because it has already been saved locally with :c:func:`PyErr_Fetch` or

+  assertion when running against a version of Python that is compiled with
+  assertions enabled.
 
 * :c:func:`PyErr_SetImportError` now sets :exc:`TypeError` when its **msg**
   argument is not set. Previously only ``NULL`` was returned with no exception
