[Haskell-beginners] Segmentation fault

[Hollister Herhold]

Just a guess, but maybe you could try updating to 10.8.3? I'm pretty sure I've seen people on the ghc-devel mailing list running 10.8.3 and things work. You could also try downloading the ghc 7.6.2 binary.

I didn't do anything fancy with Haskell, I just downloaded it yesterday and I didn't tamper with any haskell-files outside of my home-directory. The only kernel extensions I have installed are the ones from VMWare Fusion and maybe flux. (i'm not sure if flux involves kernel extensions or how deeply it messes with the OS.)
