-----------------------------------
Summary: [C++] Dataset initialization could segfault if called
simultaneously
Key: ARROW-16390
URL: https://issues.apache.org/jira/browse/ARROW-16390
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: Weston Pace
Assignee: Weston Pace
The code is doing some one-time initialization in
{{arrow::dataset::internal::Initialize}} but not properly guarding the
initialization so it might end up running twice. It's possible this is the
cause of https://github.com/apache/arrow/issues/13018
