> [R] Guard against null buffers
> ------------------------------
>
> Key: ARROW-3362
> URL: https://issues.apache.org/jira/browse/ARROW-3362
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Wes McKinney
> Assignee: Romain Francois
> Priority: Major
> Fix For: 0.12.0
>
>
> The R C++ bindings feature a number of cases where a data buffer is being
> accessed when it may possibly be null in the case of a 0-length array. This
> will cause a segfault
> https://github.com/apache/arrow/blob/master/r/src/array.cpp#L245
> I suggest defining some helper functions as we have done elsewhere to assist
> with getting a typed offset into a buffer but passing through nullptr if the
> buffer object is null
