> In the {{*arrow.StringType}} case, in the {{needTruncate}} code path (happens when writing a {{record.NewSlice}}), a reference to {{data.buffers[2]}} is appended to the payload body. It gets {{Release}}'d [here|https://github.com/apache/arrow/blob/122985841dcedd13bee5388cf5cb887f75cb4527/go/arrow/ipc/file_writer.go#L247] without any {{Retain}}.
> The code for the {{FixedWidthType}} and {{BinaryType}} cases is similar.
> The attached code reproduces the issue.
