Comment(by simonmar):
confirmed:
{{{
$ ghc -O2 5303.hs
[1 of 1] Compiling Test ( 5303.hs, 5303.o )
ghc: panic! (the 'impossible' happened)
(GHC version 7.0.3 for x86_64-unknown-linux):
funResultTy
<pred>main:Test.ApplyState{tc rrv} p{tv aBn} [sk]
~
hashed-storage-0.5.6:Storage.Hashed.Tree.Tree{tc r4V}
}}}
unfortunately I can't test with HEAD because hashed-storage doesn't
install:
{{{
$ cabal install hashed-storage
Resolving dependencies...
cabal: cannot configure dataenc-0.14. It requires base >=3.0.0 && <4.4
For the dependency on base >=3.0.0 && <4.4 there are these packages:
base-3.0.3.1, base-3.0.3.2, base-4.0.0.0, base-4.1.0.0, base-4.2.0.0,
base-4.2.0.1, base-4.2.0.2, base-4.3.0.0 and base-4.3.1.0. However none of
them are available.
