`del OSError().characters_written` raises `SystemError`: "null argument to internal routine" I don't know why anyone should try this in productive code, but since the documentation says, that every `SystemError` should be reported, I'm doing that. My suggestion would be to make that attribute behave like the other ones of `OSError`, e.g. defaulting to `None` and returning to that value on deletion. |

PR 11172 makes deleting characters_written to be as for other non-special attributes. Deleting it will be successful only if it was set before, and will raise an AttributeError otherwise. >>> e = OSError() >>> e.characters_written = 1 >>> del e.characters_written >>> del e.characters_written Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: characters_written |

Why is it using -1 instead of NULL as the "not-set-indicator"? -1 is a valid python integer, that can be assigned, even if it doesn't make sense in the context, while `None` can not, because it's missing an `__index__` method. |

PR 11175 fixes some other related SystemErrors (and segfaults). |

> Why is it using -1 instead of NULL as the "not-set-indicator"? Because the field of the C structure has integer type, and it can not be the NULL pointer. |
