#8848: Warning: Rule too complicated to desugar -------------------------------------+------------------------------------- Reporter: carter | Owner: Type: bug | Status: closed Priority: normal | Milestone: 7.10.1 Component: Compiler | Version: 7.8.1-rc2 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | simplCore/should_compile/T8848, | T8848a | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by yongqli): @thomie: We are stuck on GHC 7.8 for now :(. For what it's worth, I was able to work around the problem using the RULES method. I set the rule to fire after phase 1, so that "map2" would have already been inlined away, thus preventing an infinite loop. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8848#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
