#11822: Pattern match checker exceeded (2000000) iterations -------------------------------------+------------------------------------- Reporter: j.waldmann | Owner: gkaracha Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1-rc3 Resolution: | Keywords: | PatternMatchWarnings Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by NeilMitchell): Perhaps make it a warning that is off by default? That solves the immediate problem and lets people who do care about the new pattern match checker opt in to issues where their patterns are too complex to be properly matched. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11822#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
