Comment(by thoughtpolice):

 As I'm suffering from this problem too and it causes numerous testsuite
 failures, I've imported William's bandaid patch for the unwind frame
 warning from darcs to git, and put it here:

 http://github.com/thoughtpolice/testsuite/tree/5019-bandaid

 Since this is apparently going to require a fix to libffi upstream to
 resolve properly, it would be nice to have this integrated into the
 testsuite for the time being (or an equivalent,) but it's damn ugly.

 I'm using x86_64/GHC on OS X 10.6.8, XCode v4.0.2.
