I'm unable to reproduce it no matter how much I tried to run those tests by hand. In my last try I even used a simple go file that calls an sh file that calls make clean test … in a sub-shell and even this works. I don't know … maybe it's some asdf implementation specific issue, but it fails every time I try to call asdf install elixir ref:main.
