iOS Native Crash on UnityUseAnimatedAutorotation (TrampolineGlue)

    Hi, we're encountering a bunch of native crashes on iOS related to 
    UnityUseAnimatedAutorotation
    when using 2019.4.9f1.

    From what I can gather (based on the stacktrace below), the Trempoline is being cleaned-up on stack frame 31, and being accessed again on stack frame 0, which would probably lead to exceptions since I'd mostly a bad idea to access an object after it's cleaned-up.

    Is anyone else having this issue, or is there a known solution/work-around for this?

    We temporarily "fixed" this by not calling UnityUseAnimatedAutorotation while terminating:

    if (!isTerminating)
    [UIView setAnimationsEnabled: UnityUseAnimatedAutorotation() ? YES : NO];

    sigh not this again: apple started to do more and more things with views on app shutdown.

    >>We temporarily "fixed" this by not calling UnityUseAnimatedAutorotation while terminating:
    this is a perfectly fine fix

    can you report a bug (no need to attach project, sure) with all this information so it can be tracked?

    well this time 1) it is impossible to just reproduce 2) we have all the information 3) you can always say in the bug "alexey told me to do just this" ;-)

    anyway: 1198042 is about "Crash on Android plugin CallStatic", so i assume you meant 1278124 ;-)

    Now that sounds good ;) submitting impossible bugs to reproduce in future only ;)

    Thanks, edited!

    In Unity release 2019.4.13f1 the case number 
    1278124
    was mentioned as being fixed.

    After updating our project to this unity version, we still receive the same crash (although far less than before):

    that sounds very weird - it should be in a different place (different line)
    and i can confirm the fix should be in 2019.4.13f1

    I'm not sure if the fix was applied directly to the affected file, but I've compared the 
    UnityViewControllerBase+iOS.mm
    files of both 2019.4.13f1 and 2019.4.9f1 and there's no difference in their content...

    nono, the fix was in unity library itself

    Ended up hitting a very similar issue, in 2019.4.19f1, so far causing 1003 crashes and effecting 817 users.
    in my case the app is landscape only but looking at ours logs it happens before or after a ad is viewed by the user. so my assumption is that ad is portrait and causing it to animate into a new orientation.

    got my stack trace for it here

    Code (CSharp):
