    We're also seeing this on 2019.1, in the editor even. What was the exact nature of this issue? Is there a possible workaround for this?

    In my case, I have a skinned character model being imported from an asset bundle, and causing this crash.

    Thank you for solving this in 2018.4, but we're gonna need this in the full release 2019.2 as well. Does anyone know when 2019.2 will come out of beta?

    We are having the same problem on on 2019.1.4f1; In Editor is OK, but crashes on an iOS build with stacktrace.

    Update: In Unity 2018.4.3f1 LTS, the iOS crash now gives a different error:
    'Execution of the command buffer was aborted due to an error during execution. Caused GPU Hang Error (IOAF code 3)'

    Any date about when'll this bug fix in 2017.4 LTS? Since Google Play needs ARM64 Android build from August, and our game crashes with this problem in ARM64 build.

    I can confirm this is not resolved in 2019.2.0b7 (if anything, it's worse).

    We are having a very similar issue on 2019.1.6f1; project runs fine in editor, but crashes on an iOS build with the above stacktrace.

    I am seeing similar issues in Unity 2018.4.0f1 LTS and Unity 2018.4.1f LTS, on both Android and iOS devices. It does not happen for us in Editor, on PC nor Mac. It happens when loading assetbundles that contain 3D models which are displayed. I cannot upload the project, but here are stack traces.

    iOS Stacktrace:

    Android crash:
    05-28 12:46:37.271: E/MessageQueue(2615): IdleHandler threw exception
    05-28 12:46:37.271: E/MessageQueue(2615): java.lang.Error: signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 000000800605e620

    It would be great to have this fix moved into 2018.4 LTS.
