         isCrossStage <- if compilerStage < Stage3

                           then expr (crossStage compilerStage)

                           else pure False

-        let libraryStage = if isCrossStage then succStage compilerStage else compilerStage

+        let libraryStage = case compilerStage of

+                Stage0 {} -> Stage1

+                _         -> if isCrossStage then succStage compilerStage else compilerStage

         tgt <- expr (targetStage libraryStage)

         pure $ show tgt { tgtLocallyExecutable = not isCrossStage }
