Comment(by mvanier):

 Update: Apparently the problem is worse than I thought.  Not only the -vN
 options but also the -W command-line option, or even no command-line
 option at all, can result in a segfault.  It's also sporadic; some times
 invoking ghci works fine, other times it segfaults.  ghci -v0 seems to
 segfault every time, ghci -W or ghci with no command-line options only
 about half the time.

 This is on Mac OS X Snow Leopard 10.6.8, on a Mac Pro 64-bit machine with
 Xeon processors.  I used the 64-bit Haskell Platform.  Earlier installs of
 the Haskell Platform all worked fine, and I cleared them out before
 installing this one.
