Re: [Haskell-cafe] Hint causes GHCi linker error under Windows
Hi, Martin Do you have a complete example one can use to reproduce this behavior? (preferably a short one! :P) In any case, I'm resending your message to the glasgow-haskell-users list to see if a ghc guru recognize the error message. It is strange that the problem only manifests on Windows.... Daniel On Dec 11, 2009, at 7:04 AM, Martin Hofmann wrote:

The problem does not occur under Unix or with a compiled program. IMHO hint tries to start a second instance of GHCi which is not allowed/possible under Windows. If this is the case a more telling error message would be helpful.

Hi Daniel,
Do you have a complete example one can use to reproduce this behavior? (preferably a short one! :P)
With this code I could reproduce it in ghci.
runInterpreter $ loadModules [("SomeModule.hs", Nothing)]
Currently I am not on a Windows machine, so I can't tell you if this only occured when trying to load a specific module. I'll try it later and if so, I'll tell you. If you need more information, just let me know. Martin
The error message is:

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
