I&#39;m seeing this native crash with the following stack trace.

This happens in Android 7.0 &amp; 7.1 only. Nothing new has been added to the app, which has been in production for a few years, but with more devices being updated to Nougat this crash happens frequently now and is becoming a nuisance. 

Any advice would be appreciated.

**UPDATE 7/18:**

Still unable to get to the root of this, so I decided to purchase a device which had most occurrences and was reasonably priced, which turned out to be Samsung Galaxy J3 2017 version with Android 7.0. Unfortunately I am still unable to reproduce the crash.

I&#39;ve also made some memory usage improvements to the app in production, but the crash is still happening.

From all the comments and my own research it seems to be related to dynamically linked NDKs, but I&#39;m not using any and its hard to find out if any of the dependencies do.

I would like to share my dependencies, it would be great if other folks facing the same issue could call out if they are using one of the same dependencies - perhaps we can spot the culprit this way.

        compile &#39;com.android.support:support-v4:23.0.1&#39;

        compile(&#39;com.crashlytics.sdk.android:crashlytics:2.5.5@aar&#39;) { transitive = true; }

For folks facing the same crash, please respond in comments if you are using any of these dependencies / versions. Maybe we can single out the problem dependency.
