> Project: Apache Drill
> Issue Type: Bug
> Components: Client - C++
> Affects Versions: 1.10.0
> Reporter: Laurent Goujon
> Assignee: Laurent Goujon
> Fix For: 1.11.0
>
>
> The C++ connector crashes if the query sent to the server is invalid and the
> error message returned by the server is too long.
> The cause of the crash is a call to a {{vsprintf}} function which takes a
> fixed sized char buffer, but doesn't take a size argument.
