Iteratee, ghc 6.12/7.0 strange behaviour - epollControl: permission denied (Operation not permitted)
I am still playing with lastest iteratee and i think i found something strange. let's suppose we have a file test.hs like this: import Data.Iteratee import Data.Iteratee.IO import Data.Iteratee.Char main = fileDriver printLines "/etc/passwd" It works fine when executed via runhaskell / ghci in ghc 6.12. Compiled version in ghc 7 also works, but when i am trying to execute it via runhaskell / ghci i am getting this error: iter.hs: epollControl: permission denied (Operation not permitted) Any ideas?

Make sure you have at least GHC 7.0.2. There were some I/O manager bugs in 7.0.1. Johan
