Something else to look into is that this sounds like bad ram to me. Have
you run any memory diagnostics and/or checked to see if you're having any
HD issues? Anytime you have intermittent crashes like these I tend to
suspect hardware issues. Do you have another computer with the same OS
version you could try to reproduce the issue on?

The haskell platform installs to /usr/bin and /Library/Haskell. You can run /usr/bin/uninstall-hs to remove the Haskell Platform. Just running it does nothing - it will tell you what it's going to do and then you have to feed it the appropriate option to make it actually do the uninstall.
What's your XCode version?

Hi,
thanks for you help so far!
I have OX X Snow Leopard with all software updates installed (I checked this 5min ago). My OSX-Version is 10.6.8 . I have downloaded the 64bit version of GHC.
hmm, this is strange: i downloaded ghc-7.6.3 from http://www.haskell.org/ghc/download_ghc_7_6_3#macosx_x86_64 i did "./configure" and "sudo make install", but still it seems that I have version 7.4.2. It turns out that one installer installs into /usr/bin and the other into /usr/local/bin.

Maybe it is really this bug that just needs to be fixed and that won't just disappear on its own? http://hackage.haskell.org/trac/ghc/ticket/7212 http://hackage.haskell.org/trac/ghc/ticket/7403
DEBUGGING:
I added an echo line into /usr/local/bin/ghc-7.6.3 so it reads
#!/bin/sh exedir="/usr/local/lib/ghc-7.6.3" exeprog="ghc-stage2" executablename="$exedir/$exeprog" datadir="/usr/local/share" bindir="/usr/local/bin" topdir="/usr/local/lib/ghc-7.6.3" executablename="$exedir/ghc" echo "$executablename" -B"$topdir" ${1+"$@"} exec "$executablename" -B"$topdir" ${1+"$@"}
So I have all the ingredients to start GDB.

Sorry, I wasn't clear - I was thinking OS X 10.8.3. Your uname says
10.8.0, which I now see (after running uname on my 10.7.5 installation, it says darwin 11.4.2) has nothing to do with the version of OS X you're running, so never mind. What version of OS X *are* you running?
The Haskell Platform comes with ghc 7.4.2. The newest release version
of ghc is actually 7.6.3, and you can find the binary distributions here:
The Haskell Platform "ships" with an older version that's been "shaken
down" a little more than the latest-and-greatest ghc. It also comes with a selection of libraries that have been well-tested. You *can* start with just ghc 7.6.3 and install the libraries yourself, however. I believe the next Haskell Platform release (scheduled for May-ish, I think) will have 7.6.3, but don't quote me on that. Discussions were ongoing last I looked.
I'd suggest downloading and installing the binary for ghc 7.6.3 and see
if ghci runs on that without crashing.
Hope this helps.

Sometimes I get even 15 segmentation faults in a row, and sometimes I can open it many times and it works each time.

http://www.haskell.org/platform/ . I followed the one and only "Download" link on the homepage. The Wikipedia says that 7.6.2 is the newest version although I cannot find that version on the haskell website. It's hard for me to believe that the development version would be 3 major version numbers ahead, but maybe we are talking about different implementations? things work. You could also try downloading the ghc 7.6.2 binary. 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.)
