The same bug also manifests itself when accessing the Valid property on all sliced arrays. This is because both BooleanArray's toMATLAB method and the Valid getter function call arrow::matlab::bit::unpack(const std::shared_ptr<arrow::Buffer>& packed_buffer, int64_t length). This function calls VisitBitsUnrolled(const uint8_t* bitmap, int64_t start_offset, int64_t length, Visitor&& visit) with the assumption that start_offset is always 0. However, when the array has been sliced, start_offset will not be 0. Updating our unpack function to accept start_offset as input should fix both issues. -- This is an automated message from the Apache Git Service.
