> [C++] Buffer::mutable_data_ member uninitialized

>                 Key: ARROW-2275

>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: C++
>    Affects Versions: 0.8.0
>            Reporter: Antoine Pitrou
>            Priority: Minor

> 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()}}?)
