 The following module reproduces the error when loaded into ghci and main is executed under Windows. It works fine when compiled. \begin{code} module Main where import Language.Haskell.Interpreter main = putStrLn "File to load: " >> getLine >>= erroneousLoad erroneousLoad :: FilePath -> IO () erroneousLoad f = do ok <- runInterpreter $loadModules [f] case ok of Right _ -> return () Left e -> fail (show e) \end{code} However in my current program I also encounter strange behaviour when executing compiled code. I use 'haskeline' for a REP-loop. The user input is parsed and passed to a function similar to 'erroneousLoad'. When I type the path character by character, or when start with an empty line by pressing return, again everything works fine. When I use the completion function of 'haskeline' the program crashes with a segmentation fault. Changing the runInterpreter line to trace ("XXX " ++ (show f))$ runInterpreter $trace "YYY"$ loadModules \$ trace "ZZZ" [f] I get the following output: XXX "expl\\\\Examples.hs" Igor2.exe: internal error: evacuate(static): strange closure type 1094 (GHC version 6.10.4 for i386_unknown_mingw32) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug This application has requested the Runtime to terminate it in an unusual way, Please contact the application's support team for more information. Sometimes I get different types of the 'strange closure', e.g. 17408 or others. I was not able to reproduce those errors on a smaller example than my whole program. Under Linux none of those errors occurs. Cheers, Martin _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
