#10370: Compile time regression in OpenGLRaw -------------------------------------+------------------------------------- Reporter: michalt | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): I created a synthetic test case that exhibits the same space blow-up: {{{ modu = unlines $ "module Out where" : "import Control.Monad (forever)" : [ var ++ " :: IO (); " ++ var ++ " = forever $ putStrLn \"" ++ var ++ "\"" | n <- [1..3000], let var = "a" ++ show n ] main = writeFile "Out.hs" modu }}} The string literals seem to be important, I didn't manage to find a variation that blew up without them. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10370#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
