With a slow validate build on OSX, `PolyKinds03` fails:
{{{
cd . && '/Users/ian/ghc/7.4-branch/val64/inplace/bin/ghc-stage2' -fforce-
recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-conf
-rtsopts -fno-ghci-history -c PolyKinds03.hs >PolyKinds03.comp.stderr
2>&1
Compile failed (status 256) errors were:
ghc-stage2: panic! (the 'impossible' happened)
(GHC version 7.4.0.20120126 for x86_64-apple-darwin):
ASSERT failed! file compiler/types/Kind.lhs line 254
ghc-prim:GHC.Prim.BOX{(w) tc 347} ghc-prim:GHC.Prim.ArgKind{(w) tc 34p}
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
}}}
`PolyKinds13` fails similarly.
