[New-bugs-announce] [issue26312] Raise SystemError on programmical errors in PyArg_Parse*()

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

For now programmical errors with the use of PyArg_ParseTuple() cause raising SystemError. But some programmical errors with the use of PyArg_ParseTupleAndKeywords() cause raising RuntimeError. I think that SystemError is the correct exception type.

Proposed patch replaces RuntimeError with SystemError in PyArg_ParseTupleAndKeywords(). This change shouldn't break any code (except CPython tests for PyArg_ParseTupleAndKeywords()), because this exception never raised if PyArg_Parse*() functions are used correctly.
