It looks like sepByEnd is implemented using recursion, which results in an infinitely large production when used with Earley. Earley only supports finite grammars, and recursion (other than many and some which are special-cased) needs to be done with rule. So this is a known limitation. It's a bit unfortunate that it seems like parts of the parser-combinators library can't be used because of this limitation, but I don't see any way around it.
The reason your implementation of sepByEnd works is that sepBy is implemented using many.
