Windows Store & Phone - Exception in msvcr120d_app.dll

jotapeh_1 · November 19, 2014, 6:42pm

I’m having a really hard time figuring out where this crash is coming from. It only happens in Windows Phone and Windows Store builds, never in the Editor or other platforms (eg., iOS, Android.)

It appears to be something to do with Unity’s gfxdeviceworker.cpp. I’ve attached a screenshot of the call stack, and will happily provide more info if it helps…

It happens randomly and unfortunately there doesn’t seem to be one consistent method to reproduce it. I can’t upload this project for repro for legal reasons. Anyone have any ideas on what to do, what might cause this type of exception?

Hi,

could you post the player log or Visual Studio output? The latter would be preferable.

When you say it happens randomly, how easy is it to reproduce it? Does it happen like every 5 minutes or more like 5 hours?

Which Unity version are you on? What kind of devices do you get the crashed on (for example, were you able to reproduce it both on phone and PC, or just phone and tablets)?

And finally, could you try adding the following line at the end of App class constructor, in App.xaml.cs file - it will disable multithreaded renderer, so the stacktrace information will contain everything that lead up to the crash point:

appCallbacks.AddCommandLineArg("-force-gfx-direct");

Thank you for the speedy reply!

Building using Unity 4.5.5f1 (latest stable). The game crashes every few minutes or so. Pretty consistent during the main gameplay scene.

Consistently crashes on a Dell XPS Desktop and Surface Pro 3, and phone devices including a Nokia Lumia 520 and a Nokia Lumia 630. Building for Windows Store Universal 8.1

Here is the Call Stack with the added command line arg to disable the multithreaded renderer:

There’s your issue:

D3D11 ERROR: ID3D11DeviceContext::Map: Map cannot be called with MAP_WRITE_DISCARD access, because the Resource was not created with the D3D11_CPU_ACCESS_WRITE flag. [ RESOURCE_MANIPULATION ERROR #2097210: RESOURCE_MAP_INVALIDMAPTYPE]

Looks like Unity for some reason tries to access a vertex buffer after it’s been created and the buffer is not dynamic. It tries to map the resource to main memory, and when the mapping fails, it tries to write to invalid memory location, and thus producing a crash.

I can’t tell you exactly what is causing it - it most likely is a Unity bug. Just a wild stab in the dark - do you have dynamic batching enabled? If so, could you try disabling it?

I’ll think about this tomorrow and get back to you. It’s getting late here :).

jotapeh_1 · November 19, 2014, 8:37pm

Thanks again. I did indeed have Dynamic Batching enabled. I disabled it and unfortunately got the same crash after a couple minutes. Looks to me like this is pretty much the same:

Thanks again for looking into this, I’m completely stumped personally, but I will keep on poking.

jotapeh_1 · November 24, 2014, 4:51pm

Took a lot of digging, but I found a workaround. The issue is likely in Unity’s code for shared vertex buffers. But we can avoid them being created

Mesh.CreateSharedVBO only occurs when you have a Mesh marked for updating every frame, as in when you use Unity - Scripting API: Mesh.MarkDynamic. You can avoid CreateSharedVBO being called by simply not using this function.

I expected a performance hit, but it also turns out that Mesh.MarkDynamic() actually makes everything slower according to this thread: Huge performance loss in Mesh.CreateVBO for dynamic meshes [ IOS ] - Unity Engine - Unity Discussions

So for now, the workaround appears to be simply - don’t use Mesh.MarkDynamic().

Tautvydas-Zilys · November 25, 2014, 8:55am

Hi,

this looks like a bug in Unity, indeed. Thanks for heads up. Do you think you could submit a bug report with a repro attached?
