    I'm observing this in 5.6.2f1 on windows after building very simple 3D project utilizing mostly sprites and colliders etc for iOS. No particle systems used at all.

    I get error:
    Allocation of 35 bytes at 067502f0 UnityEditor.HostView:OnGUI()
    TLS Allocator ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations UnityEditor.HostView:OnGUI()

    A few of these warning messages:
    Allocation of 35 bytes at 067502f0

    Then finally error again:
    TLS Allocator ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations

    Playing the project after the build is done will endlessly spray the console with error:
    TLS Allocator ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations

    And these warning messages:
    Allocation of 35 bytes at 067502f0

    These error continues, regardless of switching platform to Android. The only way to get rid of these errors seems to be restarting Unity.
