Visual Studio fails to debug IL2CPP code

In smaller projects we can debug IL2CPP 64 bits code. We attach a debugger and waits for the application input. The debugger finds the symbols and you can see that it swiftly enables all breakpoints. In Unity 2019.3.1f1


In a larger application, the attachment of the debugger takes a lot longer time before the breakpoints are shown as active and if I let the application continue, the breakpoints are never hit.

This is caused by a third thread that is blocking before our code has started executing. We can see out breakpoint is set in one thread but another thread is active and taking all focus so we ca not start the application.

Anyone seen this ? We do have some shaders that fails to compile but in normal run the application starts and runs just fine.

 

If i release the debugger, the application continues and runs the application just fine


This is the output of LogCat before debugger attached..

Then it totally stopps until i relese the debugger

 

i Will. I have a git repo you can test

 

https://github.com/ToolTech/Streaming_Map_Demo

Just run the android version and select using 64 bit and il2cpp

 

This is randomly occuring. I can not reproduce now on my phone but collegues have on theirs so its a bit tricky to issue a bug. We do have other bugs we can continue to issue first

 

I issued another IL2CPP bug here (Case 1226943) Compiled with IL2CPP

 

How do you marshall bool values in a native call ?

Code (CSharp):

1.  
2. [DllImport(Platform.BRIDGE, CharSet = CharSet.Unicode, CallingConvention = CallingConvention.Cdecl)]
3. private static extern bool Texture_getMipMapImageArray(IntPtr texture_reference, bool createMipMaps, bool uncompress, ref UInt32 size, ref IntPtr native_image_data,ref ImageFormat format,ref ComponentType compType, ref UInt32 components, ref UInt32 width,ref UInt32 height,ref UInt32 depth);
4.  

The return value ? The two bool parameters ? As bytes. As shorts or as words ?
