This isn't exactly urgent but Glasgow Haskell seems to be freezing stdin in
such a way that other applications can't get at it. For example, take the following
well-known program:
main = putStr "Hello World!"
If I run this and then run a well-known SML compiler I get:
Standard ML of New Jersey v110.7 [FLINT v1.41], June 2, 1998 [CM; autoload enabled]
-
uncaught exception Io: input failed on "<stdIn>", Resource temporarily unavailable
(various other blah omitted).
Also lynx falls over (in an even less informative way). I've tried running
hw on truss but can't figure out what's going on, maybe I don't know enough
about truss. However if I replace the above Haskell program with
main = return ()
there is no problem. What is going on please?
