      Description

      dapply and gapply with Arrow optimization and Arrow 0.14 seems failing:

      > collect(dapply(df, function(rdf) { data.frame(rdf$gear + 1) }, structType("gear double")))
      Error in readBin(con, raw(), as.integer(dataLen), endian = "big") :
        invalid 'n' argument
      

      We should fix it and also test it in AppVeyor
