#7540: Panic on type inference with vectorised parallel arrays -------------------------------+-------------------------------------------- Reporter: tinctorius | Owner: Type: bug | Status: new Priority: normal | Component: Compiler Version: 7.6.1 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: Compile-time crash | Blockedby: Blocking: | Related: -------------------------------+--------------------------------------------
Comment(by tinctorius): An even simpler example: {{{ {-# LANGUAGE CPP #-} {-# LANGUAGE NoImplicitPrelude #-} {-# LANGUAGE ParallelArrays #-} module Y where import Data.Array.Parallel #ifndef BUG func :: Bool -> [:[:a:]:] #endif func True = [:[::]:] func False = func True }}} Taking `[:[::]:]` out to its own variable doesn't change a thing, unless it's given a monomorphic type signature. -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7540#comment:1> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
