Antoine Pitrou commented on ARROW-12708:
----------------------------------------

Does this still fail? Can someone post a log of CI test results? The link in the issue description doesn't work anymore.

> We've started seeing Valgrind in our R tests. I did some digging through the commits and found that these errors started when https://github.com/apache/arrow/commit/0d979bf0cbb10e4977c99a542c266134604e72a5 was merged (ARROW-12575).
> As far as I know, this is the first use of {{negate_checked}} in R, so that is the likely culprit, though I haven't been able to match the error outputs to the {{negate_checked}} code directly.
> Here's the first failure: https://dev.azure.com/ursacomputing/crossbow/_build/results?buildId=4805&view=logs&j=0da5d1d9-276d-5173-c4c4-9d4d4ed14fdb&t=d9b15392-e4ce-5e4c-0c8c-b69645229181&l=2942
