 This is a migration of [http://trac.haskell.org/haskell-
 platform/ticket/199 HP ticket #199]:

 Installation of the HP appears to have succeeded and things seem to
 compile and work fine, but GHCI frequently crashes on startup. Here:


 {{{
 GHCi, version 7.4.1: http://www.haskell.org/ghc/ :? for help
 Loading package ghc-prim ... linking ... done.
 Loading package integer-gmp ... linking ... done.
 Loading package base ... linking ... done.
 Segmentation fault
 }}}

 There's a 2-3 second delay between the last message and the segfault.
 Trying to invoke GHCI a couple of times eventually succeeds and results in
 a working REPL. I have reproduced this on two machines that ran the
 previous version just fine.

 Please see the attached [http://trac.haskell.org/haskell-
 platform/attachment/ticket/199/ghc_2012-06-03-205527_MacPro09.crash crash
 reporter log] in the original ticket: The crash appears to be in the
 garbage collector.
