I think I was unclear, I mean that I trying to access HEAP variables from outside of Module. Anyway I have a test case. It instantiate simple wasm module and print all Module keys that started from HEAP. It prints them both from inside Module and from outside. "inside" case works all times, but "outside" case works only until 2.0.10. Need to run `./test.sh`
