    I had this same issue in version 2017.3.0f3 and solved it by deleting everything from my project folder (in the explorer) EXCEPT:

    - Assets
    - ProjectSettings
    - Any Visual Studio Project/Solution Files

    I get this issue as soon as I click the play button or build the solution for iOS. Running on Windows 10, Unity version 2017.3.0f3

    TLS Allocator ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations

    I tried re-importing all assets and that didn't help. I can still build to iOS, but it makes debugging nearly impossible.

    Update:
    *Using Unity for Win
    * Reverted the Crunch submission, restarted Unity and the error is gone.
    * The error occurred while resizing the game window and running the game in editor (windows)
