> [C++] Buffer data should never be null

> Key: ARROW-4150
> URL: https://issues.apache.org/jira/browse/ARROW-4150
> Project: Apache Arrow
> Issue Type: Wish
> Components: C++
> Affects Versions: 0.11.1

> When a 0-byte buffer is allocated, or at the start of a BufferBuilder, the
> buffer's data pointer can be null. This leads to passing null arguments (with
> zero sizes) to standard functions such as memset() and memcpy() in many
> places. UBSAN doesn't like it.
> Since a null pointer often means "failed allocating" or "programmer error",
> we might want to use a non-null pointer to a static empty piece of data
> instead.
