#71: GHC panic on cabal install of darcs w/ Platform

     Type:  defect            |      Status:  new

Component:  (none-specified)  |    Keywords:  OS X, darcs
------------------------------+---------------------------------------------
 When I install GHC and the Platform from the beta .dmg, and try to do
 'cabal install darcs', I get a GHC panic:
 {{{
 ghc: panic! (the 'impossible' happened)
   (GHC version 6.10.3 for i386-apple-darwin):
         cat_evals
     base:GHC.Arr.Array{d ras}
     [ww{v aKhO} [lid], ww1{v aKhP} [lid], ww2{v aKhQ} [lid]]
     [!, !, _, _]
 }}}

 This only happens when I use the platform, and also happens when I try to
 install the tarball from the darcs website.
 If I install only GHC (either from the Platform .dmg or the GHC website)
 and zlib, HTTP and cabal-install manually, then install darcs with cabal
 install, there is no problem.
