The // refers to a previously-compiled RE and there isn't one. This is an error in your script, not sed 4.0.1-1 and should also give the same error message with sed 3.02-1. As Randall says using / separators in s commands when slashes are part of the RE is tricky. You can use pretty much any separator other than a backslash.
