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. On Apr 27, 2013, at 5:59 AM, Michael Peternell wrote:
Hey,
i did a little search.
it seems like this was already a bug 3 years ago: http://trac.haskell.org/haskeline/ticket/105 and it reappeared on a Mac in version 7.4.1 8 months ago http://hackage.haskell.org/trac/ghc/ticket/7212 someone has refiled the bug for 7.4.2 http://hackage.haskell.org/trac/ghc/ticket/7403 the bug is discussed in communities http://forums.gentoo.org/viewtopic-t-844842-start-0.html
the 7212 ticket is marked as "wontfix" and the 7403-ticket is marked as "duplicate". i don't wanna file another bug report, there are already enough of them.
please, someone fix this bug.
Regards, Michael

Hi,
sometimes when I start ghci, I just get a segmentation fault. Sometimes I get even 15 segmentation faults in a row, and sometimes I can open it many times and it works each time.
I downloaded the Haskell Platform for Mac, 64Bit, from http://www.haskell.org/platform/mac.html I verified the SHA1-Sum, btw.
I tried reinstalling the platform, and I tried deleting the ~/.ghc directory, but nothing works. 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.)

Any insights on what is really going on behind the scenes will be appreciated.
