Is this a bug in the compiler? If I uncomment the two lines I get a compile error

e: org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: org.jetbrains.kotlin.codegen.AccessorForPropertyDescriptor cannot be cast to org.jetbrains.kotlin.codegen.AccessorForPropertyBackingField
