The PyBytes_FromStringAndSize() and PyObject_GetAttrString() calls in PyCData_reduce() are not checked for failure. |

Does not Py_BuildValue() check the argument for "N" for NULL? |

Yes, N and O accept NULL and pass the exception up the call stack. It's not a bug. https://docs.python.org/3/c-api/arg.html?highlight=py_buildvalue#c.Py_BuildValue |

I'm sorry. I misunderstood the behavior of Py_BuildValue(). |

I again encountered an assertion failure that involved PyCData_reduce(). In that function, PyBytes_FromStringAndSize() may be evaluated before PyObject_GetAttrString(). If a MemoryError occurs in PyBytes_FromStringAndSize(), an assertion failure will occur in _PyType_Lookup() when PyObject_GetAttrString() is called. The assertion failure occurs before the Py_BuildValue() call. Please reopen the issue and the PR. |
