hDuplicateTo still buggy

[Volker Wysk]

Hello.

You can't replace a closed handle with hDuplicateTo:

import IO
import GHC.Handle

main = do
   hClose stdout
   h <- openFile "/tmp/out" WriteMode
   hDuplicateTo h stdout

This produces:

bug1: /tmp/out: hDuplicateTo: invalid argument (Bad file descriptor)


Bye,
V.W.
