summary:
Issue #23571: Enhance _Py_CheckFunctionResult()
Too bad, sometimes Py_FatalError() is unable to write the exception into
sys.stderr (on "AMD64 OpenIndiana 3.x" buildbot, the buildbot was probably out
of memory).
Call Py_FatalError() with a different message for the two cases (result+error,
or no result and no error).
