That entry seems to have slain the compiler.  Shall I replay
your session? I can re-run each line except the last one.

I have been able to minimise the initial example to the following code snippet, in which the classes Enum and Struct have been removed and replaced by AnyRef, and in which I avoid extra branches and nesting:

{
  type A = AnyRef { def b: B }
  type B = AnyRef { def a: A }
}

The cause of the StackOverflow error is that when the compiler starts validating the variance of the type A declaration, it expands the full declaration of type B, for which in turn it also starts validating the variance of type A again.

It should be mentioned that, if the main expression was a trait or object, as in the code below, the compiler rejects it with an "illegal cyclic reference" compile error.

trait C {
  type A = AnyRef { def b: B }
  type B = AnyRef { def a: A }
}
