#11290: T6031: *** Core Lint errors : in result of Common sub-expression *** -------------------------------------+------------------------------------- Reporter: thomie | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: | deriving/should_compile/T6031, | deriving/should_run/T7931 (WAY=hpc) Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): I think it says `warning`, but if it stops compilation, then it's a real error. And it should be: `case` expressions must have all possible alternative listed, or we have a potential type error. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11290#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
