@steveisok Any guidance or help I could be given on the llvmfullaot scenario would be appreciated. I'm not even sure how to start debugging this scenario. It passes on the basic mono legs.

@kg can you help Aaron with this?

I don't know anything about LLVM or LLVM-based AOT, do we have someone who's worked on that infrastructure still? i.e. WASM AOT
