[GitHub] [arrow-rs] alamb opened a new issue #68: Invalid mem access in BufferBuilderTrait
alamb opened a new issue #68:
URL: https://github.com/apache/arrow-rs/issues/68
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-8627
Currently, there is an invalid access happening through the append_n method to a mutable location with multiple shared refs. Happens when benchmark code executes with `bench_bool`.
Happens on (rustc 1.44.0-nightly (45d050cde 2020-04-21))
