This segfaults on Windows:

import Network.Curl (curlGetString)

main :: IO ()
main = fmap snd (curlGetString "" []) >>= putStrLn

It does not depend on options either curl package or this code is compiled with.

7.2.1 and 7.3.20111004 and definitely affected.

Compiled with 7.0.3 this example crashes when linked with -debug runtime but work pretty fine otherwise.

Investigating a little bit further I've found that:

  1. ghc 6.6.1 gives exactly the same crash
  2. ghc 6.8-6.12 give "%1 Is Not a Valid Win32 Application" error

So, the only working config is 7.0.x (no debug) and it looks pretty much accidental now. It smells like there is something wrong with win32 SSL or curl-SSL interaction.

Or, if GHC is still a culprit, this must be an extremely long standing bug.

Well, the latest and greatest stock win32 libcurl 7.22 works fine. No GHC is involved. Sorry for the inconvenience.
