Random crashes on WP8

Unity Engine
1

Hello guys,

we are currently developing bigger TD game, and on WP8 platform we are receiving random crashes in deserialization.

On any other platform we didn’t received any of those bugs.

Project randomly crashes with multiple exceptions in WinRTBridge.SerializationWeaverReader.

Exceptions:

  1. AccessViolation in Unity_Deserialize()
    That function is called by unity, so i’m sure there cannot be some type of memory corruption from multithreading or something like that.

  2. The file “none” is Corrupted! Remove it and launch unity again!
    Randomly crashes, i have tracked it too into unity deserialization.
    What is strange, sometimes is reads bad int value like (433452342) for array size, which causes
    OutOfMemory.

  3. KeyNotFound in WinRTBridge.GCGandles.Release(int)
    This is kind of first chance exception, but sometimes application crashes after continue from this exception.

All exceptions are from System namespace.

As i said, i have never had those problems on iOS, Android and Webplayer, so this must be platform specific bug.
I have checked bugtracker and there are a lot of bugs, but nothing from mentioned there and i want to know, if somebody found some of those bugs.

Thanks for support :slight_smile:

Hi,

we actually just fixed a bug on friday that sounds exactly like first two cases you mentioned. It should be available in 4.5.6p1.

As for the third issue - how consistently are you getting it?

Thanks for reply,
third issue is too random, about 20 level loads until exception is thrown sometimes more sometime less…, but i think it’s in try/catch block, because sometimes i can continue without crash, or memory corrupt. Maybe Visual Studio catched exception inside DLL and game crashed in code somewhere else…
