    Hi,

    We're very close to submitting our game, and unfortunately are being hit by a very weird crash on start up.
    We've had instances of it for a couple of weeks but more recently it has started to happen very regularly, on quite a few devices and OS versions (8+).
    After trying many, many things I ended up loading into an empty scene, and it still occurs, at which point I'm not sure what to try next.

    Here is the callstack, it's crashing in the UnityPreloadThread:
    #0 0x0000000102e3e14c in il2cpp::vm::Class::HasParent(TypeInfo*, TypeInfo*) [inlined] at /Users/builduser/buildslave/unity/build/Tools/il2cpp/il2cpp/libil2cpp/vm/Class.h:110

    #12 0x00000001027a78f4 in ::RunThreadWrapper() at /Users/builduser/buildslave/unity/build/Runtime/Threads/Thread.cpp:40

    The output is pretty much empty (apart from some Metal related shader compiling warnings).

    Anyone has encountered this one before?

    Thanks,

    G.

    Ha! It looks like Unity is not coping with an initial scene that loads too fast.
    As soon as I put an object in there with a fair amount of references (therefore taking longer to load) the problem goes away!

    Hi, could you check if the original problem is reproducible on Unity 5.3.0? If yes, it would be great if you submitted a bug report with a reproduction project.

    Hello!

    Unfortunately I can't really at the moment as we're really up against it!
    I'll loop back when I get to it though!

    Any progress on this one?

    We're having the same problem on Unity 5.3.0f4 and are now unable to run on game on iOS. (It's the same on all our test devices)

    This looks like a known bug that was corrected in 5.3.1p1. You should be able to try that release here: http://unity3d.com/unity/qa/patch-releases

    Hi Josh

    Thanks for the fast reply. Installing the patch release did solve this problem. Thanks!

    Kind regards

    Is there any chance that this fix will be added as a 5.2 patch release? We have had so many issues since moving to 5.x that we really don't want to move to 5.3 to fix this issue and potentially cause us a bunch of new ones.

    Unfortunately we're not planning to ship any more 5.2 patch releases. It is possible to build and ship special versions if necessary. I'm not entirely sure about that process, can you ping someone from our support team? If not, I'll see what I can find.

    Are you seeing the same crash described here? We did have one known bug in 5.3.2 that was corrected in 5.3.2p2. If you can provide the call stack for the crash you see I should be able to determine if it is the bug we corrected.
