Steps to reproduce:

1. Open attached project
2. Build the scene to iOS with IL2CPP scripting backend
3. Build the generated Xcode project
4. Notice the build fails and spews this error three times: 'Member reference type 'intptr_t' (aka 'long') is not a pointer'

Note:
The attached 'ScriptProject.zip' is Visual Studio project used to build the TestAll.dll. You can check it's source code there in 'ScriptProject/TestAll/Class1.cs'
With Mono backend, the build works fine.
