I've got the same problem as you. There were actualy something wrong with regex-posix-0.94.2... So I installed newer version of this packeg by cabal
> cabal install regex-posix And then I've found (thanks to ghc-pkg check and gch-pkg find-module regex-posix) that there is still old regex-posix-0.94.2...conf somewhere in my Application Data dir (under my Windows profile). So I tried to replace it with newer conf file and than everything goes wrong. I even couldn't start ghci. I have to gave this file back. I now have two independent conf files for regex-posix package. Something like: ...\Application Data\ghci\i386-mingw32-6.12.3\package.conf.d\regex-posix-0.94.2...conf ...\Application Data\ghci\i386-mingw32-6.12.3\package.conf.d\regex-posix-0.94.4...conf And now everything works fine. You might try this. Don't exactly know where the problem is, but it doesn't even matter now.
