Wes McKinney created ARROW-3362:
-----------------------------------
Summary: [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
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
