dmdTransformDictSelSig panic
Installing xmlhtml
with HEAD panicks, while it works in 7.6.3.
ghc: panic! (the 'impossible' happened)
(GHC version 7.7.20130918 for x86_64-unknown-linux):
dmdTransformDictSelSig: split failed
I reduced this panic to four files:
Common.hs
module Common where
import Data.String (fromString)
encodingName :: String
encodingName = fromString ""
Meta.hs
{-# OPTIONS_GHC -O0 #-}
module Meta where
import Data.String
Parse.hs
module Parse where
import Meta
XmlHtml.hs
module XmlHtml where
import Parse
import Common
Remove *.hi and *.o files and compile ghc -O XmlHtml
to get the panic.
