Hello, Your first problem is just a line buffering issue. You need to explicitly set the line buffer inside the child processes: redir fstdin stdInput hSetBuffering stdin LineBuffering redir fstdout stdOutput hSetBuffering stdout LineBuffering This is because the forked child process in not hooked up to a tty, so GHC decides that block buffering would be a good choice. Once you fix that you will encounter some new race condition type bugs. These bugs will show up, even *without* the -threaded flag. hth, j. At Wed, 28 Feb 2007 13:29:17 -0600, John Goerzen wrote:

You can see my test case with:
darcs get '--tag=glasgow ml' http://darcs.complete.org/hsh ghc -fglasgow-exts --make -o test2 test2.hs
I get an erro when I use that darcs command-line, and test2.hs does not appear to be in the directory afterwards. Am I doing something wrong ?
Oops. I hadn't pushed out that tag yet. It's there now.
