I found the bug! It appears allocations for new chunked arrays don't account for the `BooleanType.byte_width()` returning 0: https://github.com/apache/arrow/blob/6a0414bd9a91e890ec6a45369bf61f405180628c/cpp/src/arrow/type.h#L608-L609 https://github.com/apache/arrow/blob/6a0414bd9a91e890ec6a45369bf61f405180628c/cpp/src/arrow/type.h#L186-L192 This results in the allocation of a chunk with 0 bytes in it, but with the length declared to that of the original chunk. Example in `ForwardFillChunked.Exec()`: https://github.com/apache/arrow/blob/6a0414bd9a91e890ec6a45369bf61f405180628c/cpp/src/arrow/compute/kernels/vector_replace.cc#L693-L699 -- This is an automated message from the Apache Git Service.
