Reproduction steps:
1. Open the attached project.
2. Try to build it to IL2CPP platform (Tested with iOS and macOS).

Actual behavior:
- Build fails with nondescript error message: IL2CPP error for type <PrivateImplementationDetails>/$ArrayType=24' in assembly '.../com.unity.render-pipelines.wcfrp.Runtime.dll'
- Full error log attached in the edit below.

Notes:
- I was able to test it only on the 2018.2.0f2 version of Unity. Plugin related errors stop the build on other Unity versions. Original issue disappears when plugins are stripped.
