#7802: kindFunResult in monad transformer -------------------------------+-------------------------------------------- Reporter: tobsan | Owner: Type: bug | Status: closed Priority: normal | Component: Compiler (Type checker) Version: 7.6.1 | Resolution: duplicate Keywords: | Os: Linux Architecture: x86_64 (amd64) | Failure: Compile-time crash Blockedby: | Blocking: Related: | -------------------------------+-------------------------------------------- Changes (by monoidal): * status: new => closed * resolution: => duplicate Comment: Thanks for the report. In fact "getptrval = liftM2 lift" is enough to trigger panic in GHC 7.6. This is fixed in the development version (bugs #7368, #7441). [You might have wanted something like `liftM2 (\a b -> lift (readArray a b)) (gets mem) (gets ptr)` but I did not check whether that works.] -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7802#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
