GHCI Startup Crash with HP 2012.2.0.0 on 64bit OS X 10.6

This is a migration of 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 crash reporter log in the original ticket: The crash appears to be in the garbage collector.

Thanks for the report, but I think XCode 3.2.6 is too old. http://www.haskell.org/ghc/download_ghc_7_4_1#macosx_x86_64 says you need 4.1 to use our binaries.

So I installed GHC 7.6.3 (which is missing from the version field below, btw) and XCode 4.2 (the newest thing available for OSX 10.6.8), and I'm observing the same intermittent crash. 64-bit version.

So either 7.6 needs an even newer XCode than 7.4 (why?) and the website needs another update, or the issue is not with an old XCode; instead it's with 10.6 in general. Which would be a real pity.

Since there aren't any reports of ghci segmentation faults with 7.8.3 or HEAD on Mac, and we there won't be another 7.6 release, I'm closing this issue.
