Elixir v1.19.0-rc.1 released

I am getting:

== Compilation error in file lib/myfile.ex ==
** (CompileError) elixir_compiler_304: undefined function '__aliases__'/1 in '__MODULE__'/1
    (stdlib 7.1) lists.erl:2641: :lists.foreach_1/2

I haven’t been able to reduce this to a test case yet, curious if anyone else is seeing something like this.
