> [C++] Buffer::mutable_data_ member uninitialized
> ------------------------------------------------
>
> Key: ARROW-2275
> URL: https://issues.apache.org/jira/browse/ARROW-2275
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.8.0
> Reporter: Antoine Pitrou
> Priority: Minor
> Labels: pull-request-available
>
> For immutable buffers (i.e. most of them), the {{mutable_data_}} member is uninitialized. If the user calls {{mutable_data()}} by mistake on such a buffer, they will get a bogus pointer back.
> This is exacerbated by the Tensor API whose const and non-const {{raw_data()}} methods return different things...
> (also an idea: add a DCHECK for mutability before returning from {{mutable_data()}}?)
