[jira] [Commented] (ARROW-1524) [C++] More graceful solution for handling non-zero offsets on inputs and outputs in compute library

["Wes McKinney (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-1524?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16217428#comment-16217428 ] 

Wes McKinney commented on ARROW-1524:
-------------------------------------

This is quite urgent as many of the cast kernel implementations do not properly account for the offset, and so if used on sliced arrays at present will yield incorrect results

> Currently we must remember to shift by the offset. We should add some inline utility functions to centralize this logic.
