Hi Jon,

You're more likely to get a useful response over on the glasgow-haskell-users mailing list, as it looks like this is a GHC specific bug: http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

Running this at -N6 doesn't want to complete for me, so I'm not sure if it would segfault. I'm on a 64-bit Intel Mac OS X using GHC 6.12, dual core.

With such a small example as this your best bet would be to file a bug report:

http://hackage.haskell.org/trac/ghc/

You'll need to use the login guest/guest to file a new ticket.

Here's a paste-bin link for the code in question: http://hpaste.org/fastcgi/hpaste.fcgi/view?id=14871#a14871

-N6 finally completed. I'm using GHC 6.12 on Inter, dual-core mac-book. I'm not sure how comparable my setup is to what you tried. Antoine
