Cryptic compiling error with coverage enabled #456
Description
Apologies if this not the right place to raise this issue. With the release of Scala 3.2.0, I'm getting an extremely cryptic / ambiguous error only when compiling after running the coverage sbt command. Any idea what might be causing this?
