    I'm having a hard time to debug a crash in our app. Our app is crashing in devices with iOS 9 and 10 when the user performs multitask and kill the app. So the issue is not that critical but it messes with our crash free statistics.

    To get the things a little harder, we are only able to reproduce this issue when the app is downloaded from App Store.

    Before I start telling about the crash, let's provide some context about the app.
    This is a native iOS app where we integrated Unity using a solution almost identical to this one: https://github.com/jiulongw/swift-unity/
    There were no issues with the Unity 2017.1, but we had to upgrade the Unity version to use the new Vuforia features. We tried many Unity versions from 2017.3.1 up to 2017.4.1f1 without lucky.

    Repro steps:
    1) Download the app from App Store
    2) Run the app
    3) Perform multitask and kill the app
    Repro rate in iOS 9 and 10 are 100%!

    It's not practical to test our builds releasing the app in AppStore, so we need to find a way to reproduce this locally.

    Things we tried:
    1) Build using xcode (debug developer schema)
    2) Build using xcode (release production schema)
    3) Upload a build to testflight and check for crash logs in the device
    4) Tried to download the app from app store and then replace with one of the xcode/testflight
    5) Tried to uninstall the app store build first and then installed the one of the xcode/testflight
    3) Repeated these steps like a trillion of times in multiple devices

    The crash logs are attached at the end of my post. But what I can't understand is how a testflgith build is different from an app store build.

    Maybe the iOS handle the app differently when downloaded from app store?

    Crashlytics pointed out these crashes as heap corruption. From the logs it rly looks like that there is something trying to free a string that was already deallocated. But if we are able to reproduce this in production, the same issue would have to happen at least in a testflight build. At this point this make no sense anymore.

    Sound like a tough one man. On my builds I've had very good success with debugging on test flight.

    Just to confirm, were you able to try the exact same build as a test flight release with no issue and then try that exact build on the app store with different behavior? There's no chance some other difference could have popped in by trying slightly different builds?

    We find out that this issue is related to the Vuforia.
    We were able to reproduce this issue in an empty project just by enabling Vuforia:
    https://forum.unity.com/threads/unity-vuforia-ios-crash-on-exit-urgent.529767/

    Unfortunately, the new Vuforia plugin is integrated inside Unity so we don't have access to the C# code... We are digging inside the Vuforia auto-generated files by il2cpp, but no luck yet to pinpoint what's causing the issue.
    I believe that's is related to Vuforia deinitialization, but's only a guess since the crash happens when we kill the app.
