Lancern opened a new issue, #48062: URL: https://github.com/apache/arrow/issues/48062
### Describe the bug, including details regarding any error messages, version, and platform. In function `arrow::compute::MakeExecBatch` it checks for the input Datum's type id: https://github.com/apache/arrow/blob/5eaf553bfc7aa639fd67bd622b6b808e71fbba39/cpp/src/arrow/compute/expression.cc#L690 `Datum::type()` can return null pointers. This will happen when the Datum is constructed from a record batch or a table: https://github.com/apache/arrow/blob/5eaf553bfc7aa639fd67bd622b6b808e71fbba39/cpp/src/arrow/datum.cc#L76-L88 However, the `MakeExecBatch` function does not check whether the datum is a table before `Datum::type()` is used. This leads to a null pointer dereference when the `id()` function is called. I suggest we additionally check that `Datum::type()` does not return a null pointer before calling `id()` on it. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
