"Dynamic array capacity overflow" when loading scene directly

    Hi,

    before I start trying to cut down our 60gig project to get some reasonable test to submit a bug report.......

    Anyone seen a freeze of Unity 5.3.1p2 (happened since around 5.3.0) when loading certain scene files directly during startup of the editor? In the log, there is some complaining about an array overflow that looks like someone allocates a negative number. (see below).

    Odd thing is, when I load the project in an empty scene and then switch to the same other scene, it works fine.

    Code (csharp):
    1.  
    2. System memory in use before: 329.6 MB.
    3. System memory in use after: 329.9 MB.
    4.  
    5. Unloading 391 unused Assets to reduce memory usage. Loaded Objects now: 50141.

    7.  
    8. Load scene 'Assets/Test/ImiTest/ImiTest.unity' time: 12174.025391 ms

    Yep - our project has just started doing this too - very similar output. Seems to happen in both 5.2.4f1 and 5.3.1p3.

    Clearing out the Library folder is a temp fix for us.

    I'm also getting this, but not when loading a scene. It's while creating and destroying HyperText objects.

    I've made a stand-alone Development build, and attached the VS debugger to get a CPP callstack. Here is the result of the crash:

    Code (csharp):
    1.  
    2. >    Test.exe!UI::DepthSortGrid::AddAndGetDepthFor(const UI::RenderableUIInstruction & instruction, const UI::RenderableUIInstruction * inputInstructions) Line 189    C++
    3.     Test.exe!UI::PrepareDepthEntries(const UI::RenderableUIInstruction * uiInstruction, unsigned int count, UI::DepthSortEntry * output) Line 241    C++
    4.     Test.exe!UI::SortForBatching(const UI::RenderableUIInstruction * inputInstructions, int count, UI::RenderableUIInstruction * outputInstructions) Line 260    C++
    5.     Test.exe!UI::SortForBatchingJob(UI::SortingJobData * data) Line 151    C++
    6.     Test.exe!JobQueue::Exec(JobInfo * info, __int64 tag, int count) Line 347    C++
    7.     Test.exe!JobQueue::ProcessJobs(void * profInfo, bool * insideFrame) Line 717    C++
    8.     Test.exe!JobQueue::WorkLoop(void * data) Line 759    C++
    9.     Test.exe!Thread::RunThreadWrapper(void * ptr) Line 44    C++
    10.  
    And I've made a core dump, here: http://we.tl/po735Zvm31
    Here is the crash report from the game: http://we.tl/RBGllgktaA

    Final addition, we've managed to work-around this crash by enabling "alignByGeometry" in the TextGenerator. Hope this gives you Unity devs enough info to figure out the crash.

    Did anything happen with this? - this seems like a problem with the text rendering - I'm seeing pretty much the same thing as described above and from my initial tests it looks like the problem disappears when selecting "alignByGeometry" on one of our icon prefabs that also contains a text field. I'm using 5.3.3f1 for what it's worth

    Great thanks for your inspiration ! We found the ContentSizeFitter component attached to Text node will also cause crash traced by "UI:depthSortGrid::AddAndGetDepthFor", especially at the first UI at startup. That puzzled really a long time.
