    Thanks for sharing this information with us.
    Android developers should be comfortable debugging native crash stack, but they can crash the JVM.

    Is this fixed in 2018.3? Has anyone tried? I am on 2018.2.2f1 and still having this issue. And does not want to update to 2018.3 unless this issue has been resolved.
