#12790: GHC 8.0.1 uses copious amounts of RAM and time when trying to compile lambdabot-haskell-plugins -------------------------------------+------------------------------------- Reporter: clint | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): That's very helpful. Alas, `parsec-3.1.11` doesn't compile with HEAD. I get {{{ Text\Parsec\Token.hs:524:27: error: Could not deduce (Stream s m t0) arising from a use of option from the context: Stream s m Char bound by the type signature for: makeTokenParser :: Stream s m Char => GenLanguageDef s u m -> GenTokenParser s u m at Text\Parsec\Token.hs:(351,1)-(352,63) The type variable t0 is ambiguous }}} I have not investigated what the problem is. Does anyone know? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12790#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
